Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
I restarted my computer and launched icedove. The folder pane was present but empty
while the messages pane just showed one e-mail with a non-working read e-mail button.

   * What exactly did you do (or not do) that was effective (or ineffective)?
Searched the Internet for similar problems. Tried removing session.json and folders.json.
Tried a few add-ons that were supposed to be able to help. Purged Icedove and reinstalled.
Installed the version from Sid.

Tried starting from Konsole. Got this message:
(process:23945): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed

Tried starting from Konsole using icedove -jsconsole and got this message in the error console:
Timestamp: 17/10/14 03:02:07 PM
Warning: mutating the [[Prototype]] of an object will cause your code to run very slowly; instead create the object with the correct initial [[Prototype]] value using Object.create
Source File: resource://gre/components/steelApplication.js
Line: 783

Searched for Application.js. Closest I could find was in /usr/local/sushi. Tried reinstalling
sushi and found that it wasn't installed. Installed it. After that had no impact, I purged
sushi.

   * What was the outcome of this action?
The problem still exists.

   * What outcome did you expect instead?
I want a way to be able to access my e-mail. Right now Icedove is useless.

I finally managed to get my folders back, restarted icedove, and they
vanished again. This time a simpler fix did the trick. I changed the
view | folders to unread then restarted icedove. When a new e-mail came
in, the folder showed up. Then I reset it to all and they are visible again.

I'm not sure if this is the same bug or just a related one. However,
it's definitely a royal pain to have to keep playing around trying to
restore the folders pane.

Hello Gary!

What happen is you restart Icedove with the option "-safe-mode" from a
command line? This disables all plugin for the next session.

What plugins do you have running?

Are this plugins all installed from the Debian archives or have you some
plugins manually installed.

This behavior is "normal", this doesn't come from Icedove. This message
commes from the glibc.

The hint says that the internal usage of functions and prototypes is not
correct. This is upstream related and is depended on the internal
restructure done by Mozilla.

shushi has nothing to with Icedove. And /usr/local/... is nothing that
come from any official Debian package. ;)

The steelApplication.js is shipped within the upstream sources:

The same things happened. The only plug-ins I was using were the ones
I'd installed trying to fix the problem. They are all currently disabled.
OK. I can vouch that it does make Icedove very slow.
Well, I've already upgraded to Sid for Iecdove to try to fix the
problem. Should I revert to Jessie's version?

thanks

I set the severity to important because this issue is currently only
reported once.

You didn't answered the other questions ...
And one more ... did this happen if you create a fresh new profile?
Please backup your old settings before!

Well, I mostly run versions from unstable/experiemntal and never had
such problems. So testing a version from unstable is even better, if
a problem happen we will try to fix it in one of the next versions.

Are there bugs inside the Mozilla bugtracker about this behavior you
describe?  If there is really a issue than there should be other users
that reported such problems. It would be really helpful if you check the
bugtracker on Mozilla and provide a link to a upstream reported bug.

Regards
Carsten

I was not running any plugins when the problem first occurred. I
installed some plugins that were recommended by some sites as a
potential fix. They were Folderpane Tools and Maximize Message Pane.
They didn't fix the problem so I disabled them. I got them through the
Get Add-ons panel.

I created a new profile and it worked, which told me the problem was
with the settings. Unfortunately it was past midnight when I got the
folder pane back and I don't remember exactly what worked.

However, it went blank again following a restart of icedove. This time
the pane was recovered using one of the more usual fixes. This problem
recurs every time I start icedove. I fix it by setting the View |
Folders to unread, restart icedove then change the View | Folders back
to all.
Unfortunately the version I'm running right now is from sid. It's slow,
as the message I get on the error console warns it might be.
No. The issue however is a known one from earlier versions. I'm
surprised to see it resurfacing.

Hi,

Switching to View > Folder > Unread, restarting icedove, and switching
back to View > Folder > Unified works around the issue for me just as
others have reported. I believe this is because there is a problem
with one or more folders being inaccessible that only causes this bug
when first starting icedove, but not thereafter. The solution for me
is to fix the folder issue by unsubscribing them.

I noticed that one IMAP server account (MS Exchange) has folders in
Trash that icedove showed in the Unified Folder view, but threw an
error upon opening Trash (sorry, no longer have exact error text, but
the essence was that the folder was not accessible). I used Subscribe
to unsubscribe these folders (which I noticed were italicized, unlike
the others, but still had the checkbox selected) then exited icedove,
then started again.  After restarting, I can see all folders in the
Unified view again, and opening Trash no longer throws errors. When I
subsequently check "Subscribe", the inaccessible folders are gone from
the list entirely.

I know I'm using a version no longer in experimental right now
(leftover from an earlier attempt to solve this issue) but am
hopeful that now that I have found this workaround, it would work with
other versions too. Also, maybe it will give enough info to upstream
to find a proper fix for the issue.

I don't know exactly what caused the issue to begin with. If I have a
moment, I'll do some more tests to see if I can reproduce it and
report my findings here.

Thanks,
Ben

Steps to reproduce are not 100% reliable:

- With View > Folder > Unified selected,
- Open an MS Exchange Server IMAP account
- Delete a subfolder (was Projects > 068)
- Open Trash
- A passive error dialog shows:
  - "The current operation on '068' did not
    succeed. The mail server for account BArmstrong@dymaxion.ca
    responded: Trash/068 doesn't exist"
  - Message varies. Sometimes the server calls it 'Trash^068'. I can't
    seem to find the pattern here.
- Restart icedove
- I know that at least once after I did this, the folder pane was
  empty after restarting icedove. However, in subsequent tests I
  couldn't reproduce it anymore. Unfortunately, I might have destroyed
  my reproducible case by emptying the Trash at one point, as I can
  no longer reproduce the issue throwing away other folders.
- Sometimes after throwing away a folder, it still appears in the
  folder list in its original location, only greyed out and italicized.
  A second attempt to throw it away succeeds.

So something (or maybe multiple things) about MS Exchange IMAP
relating to folder deletion is very flaky and seems to contribute to
this bug.

Hope this helps.

Ben

Hello,

this report is quite old and I guess the reported issues are'nt alive so
I'd like to close this report.
Any news on this?

Funny you should ask. I've been away for several days and just restarted
my computer. When I started up Thunderbird, I got a similar problem. I
seemed to only have one account and there was nothing in the
accounts/folders pane. Shutting down Thunderbird and restarting it
brought everything back.

I've actually seen this happen a few times recently, with the same cure.
I'm not sure if it's related to my having the accounts on an NFS share...
