I have recently received a notification in my system mail related to
an unhandled exception in a backintime Python script.

Here is the transcript:
-----

Unhandled exception in thread started by <function
__log_keyring_warning at 0x7fdf90288488>
Traceback (most recent call last):
File "/usr/share/backintime/common/tools.py", line 1458, in
__log_keyring_warning
TypeError: 'NoneType' object is not callable

-----

This is the first time I have seen (or noticed) such a message.
It has not happened again since.

The notification was sent by the cron daemon on date Mon, 21 Jun
2021 11:00:02 -0300.

The last backintime log entry was for a snapshot taken at Mon Jun 21
07:15:01 2021 local time and does not show any errors.

The crontab script is a system entry generated by the GUI and the
python script is part of the application's installation.

[code]
#Back In Time system entry, this will be edited by the gui:
60 */15 * * * * /usr/bin/nice -n 19 /usr/bin/ionice -c2 -n7
/usr/bin/backintime backup-job >/dev/null
[/code]

Python installed version is 2.7.16 (default, Oct 10 2019, 22:02:15).

I have reported this issue to
https://github.com/bit-team/backintime/issues:

[url]https://github.com/bit-team/backintime/issues/1169[/url]

Later on I found that it had *also* been reported back in 10/2017:

[url]https://github.com/bit-team/backintime/issues/820[/url]

The OP's report is virtually identical to the one I filed and
included messages from --debug:

[code]
Unhandled exception in thread started by <function
__log_keyring_warning at 0x7fd698dbf400>
Traceback (most recent call last):
File "/usr/share/backintime/common/tools.py", line 1463, in
__log_keyring_warning
File "", line 2237, in _find_and_load
File "", line 2222, in _find_and_load_unlocked
File "", line 2150, in _find_spec
TypeError: 'NoneType' object is not callable
[/code]

The OP's report did not have any subsequent follow-up from the
maintainers of the backintime package.

Thanks in advance,

I have received yet another notification in my system mail related
to an unhandled exception in a backintime Python script.

Here is the transcript:
Unhandled exception in thread started by <function
__log_keyring_warning at 0x7f87bbb63488>
Traceback (most recent call last):
  File "/usr/share/backintime/common/tools.py", line 1458, in
__log_keyring_warning
TypeError: 'NoneType' object is not callable

As you will gather from the transcript, it is the same problem (line
1458) in file "/usr/share/backintime/common/tools.py".

FYI, here are the last 12 lines from the file file metioned above:


[code]

1456
1457 def __log_keyring_warning():
1458     from time import sleep
1459     sleep(0.1)
1460     logger.warning('import keyring failed')
1461
1462 if keyring is None and keyring_warn:
1463     #delay warning to give logger some time to import
1464     import _thread
1465     _thread.start_new_thread(__log_keyring_warning, ())
1466     # logger.warning('import keyring failed')
1467

[/code]

Thanks in advance,

This could be fixed with 1.3.3.

Could you please check this and report back.

This unhandled exception only happens every so often, totally at
random/with no discernible pattern so testing and reporting will be
more a lottery than anything else.

It can happen in a fortnight or twice within a three day span.
Unfortunately, I have *not* been able to reproduce it.

That said, for various reasons, I am running Buster on a backported
kernel.

Installing backintime-common 1.3.3. and backintime-qt will wreak
havoc in my installation.

Thanks for your input.

Best,

sawbona
