Description fake.name 2023-04-24 21:39:25 UTC

Application: kalendar (23.04.0)

Qt Version: 5.15.9

Windowing System: Wayland

-- Information about the crash:
Whenever I attempt to edit tasks in any way, Kalendar immediately crashes. Korganizer does not have any problems doing so. The crash occurs the second the change is made, before saving is even possible.

The crash can be reproduced every time.

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

These are unfortunately not very interesting, but if you can reproduce the crash, can you please install the debugging info for kf5itemmodels (libkf5itemmodels5 or somesuch) and libkpim5akonadicore and post the backtrace? These are probably the culprits.
