Description joerg 2023-02-19 09:45:49 UTC 
Application: kalendar (22.12.2)

Operating System: Linux 6.1.12-alderlake-xanmod1-1 x86_64
Windowing System: Wayland
Distribution: Arch Linux

-- Information about the crash:
Since Kalendar version 22.12.x I encounter unexpected crashes when unlocking the screen. The crash appears after the program was running for a while; it dosen't crash every time when the screen is unlocked. The crashes dosen't occur with version 22.08.x

The crash can be reproduced sometimes.

-- Backtrace:
Application: Kalendar (kalendar), signal: Segmentation fault

Fix crashes in incidenceoccurrencemodel

The cause for these crashes is that the QPersistentModelIndex get
invalided at some point and then the row is -1 which is invalid.
This is probably caused by bugs somewhere in ETMCalendar.

The previous code which tried to only update part of the model,
which in theory should be faster was wrong since a dataChanged on the
source model could result in less or more entry due to the recurrence
rules changing or in a different hash due to the start or end date
changing.

Crash with Kalendar 23.04.0

Kalendar 23.04.0 is still crashing, so the issue seems not to have been fixed unfortunately.
Comment 18 pedrud 2023-05-15 19:31:58 UTC 
Of the various Kalendar bugs with seg faults, this one is closest to my issues. If the devs think this warrants a new bug, I am happy to delete this and start a new one. 

Kalendar crashes multiple times a day for me. Often when I log back in, but also at random moments whilst I am working. 

Kalendar version: 23.04.0

Qt: 5.15.9
