Description Riccardo Robecchi 2022-12-27 10:05:18 UTC

Application: kalendar (22.12.0)

Qt Version: 5.15.7
Frameworks Version: 5.101.0
Operating System: Linux 6.1.0-x64v2-xanmod1 x86_64
Windowing System: X11
Distribution: KDE neon 5.26

-- Information about the crash:
Kalendar crashed while sitting idle in the background. No action was taken as the computer was completely idle.
After the crash, I started Kalendar again, but it stopped showing available calendars, despite them being correctly reported in the "accounts" section. I then closed it to see if starting it again would fix the issue, but then it wouldn't start again.

The reporter is unsure if this crash is reproducible.

Third backtrace (22.12.1)

Here's another one. The interesting bit is that in the meantime I have updated Kalendar to version 22.12.1.

Crash with Kalendar 22.12.2

Uploading new crash as it's related to the new version (and I don't know if there were any changes).
