Bug 467025

Application: kalendar (22.12.3)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.14-1-liquorix-amd64 x86_64
Windowing System: X11
Distribution: Debian GNU/Linux 12 (bookworm)
DrKonqi: 5.27.2 [KCrashBackend]

-- Information about the crash:
I have been cycling between views in order to get visual updates in the calendar. This has been neccessitated by some sort of visual update bug introduced after a recent update. While switching between views does result in the calendar updating, rapid switching results in a crash around 50% of the time. The calender being displayed and updated is synced to a local Nextcloud instance.

The crash can be reproduced sometimes.

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