Dear Debian folks,


while composing a message Evolution 3.4.3 crashed.

        $ dmesg
        […]
        [ 1775.978900] pool[10745]: segfault at 4 ip 00000000f6ab09c6 sp 00000000e9927e20 error 4 in libcamel-1.2.so.33.0.0[f6a03000+103000]

The backtrace can be found in the upstream report I reported [1].

I did not experience any crashes with Evolution 3.2.2 for a long time.

Crashes cause data loss, when the user currently composes a message.
Auto saving messages and restoring them only helps a little.

Crashes should never happen with the most used applications, which I am
counting the mail program to.


Thanks,

Paul

Control: severity -1 important
Control: tag -1 unreproducible

Well, it does prevent the data loss, at least.

In a perfect world, indeed. But that's not the case. Considering the
fact that it was not possible to reproduce the bug and that there were
not data loss thanks to the autosave mechanism, I'm lowering the
severity and tagging accordingly.

Regards,

Dear Yves-Alexis,


sorry for the late reply.

I still experience this. Sometimes more, sometimes less. I even was able
to reproduce this on a different system. Most developers do not seem to
use Evolution and prefer mutt or Icedove. So I claim, that is the reason
that this is not noticed this much. Non-developer users just start
Evolution from the icon and do not know how to report bugs.

Actually only if you are lucky. It seems auto-saving only happens after
x minutes and if you type fast or copy something in that interval and
delete the source before the x minutes are over the data is lost.

As written above. I now found two (over four years old) systems that
show this behavior. Do you have a lot of IMAP and POP3 accounts?

Here some more information.

1. The crash never happens when being offline. Therefore I start
Evolution using `evolution --offline`.

2. The crash happens more often, when trying to compose a message (Ctrl
+ r or Ctrl + n) when just going online and a lot of messages (from
lists) are downloaded.

I am pretty sure there is a memory leak somewhere, as I get segmentation
faults and bus errors. Unfortunately Valgrind seems to have a bug, where
it does not find installed debugging symbols [1]. So this does not get
me further.

Here is an excerpt from `/var/log/kern.log`.

Due to the Valgrind bug [1] I am currently stuck with debugging this. So
any help is appreciated.


Thanks,

Paul
