Bug 464877

Application: kalendar (22.12.1)

Qt Version: 5.15.8
Frameworks Version: 5.102.0
Operating System: Linux 6.1.8-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.26.5 [KCrashBackend]

-- Information about the crash:
It seems that Tasks cannot have a timespan, only can be set for a whole day, or user can set the end timestamp. I set an end timestamp to a task, saved it and tried to extend the task rectangle with a mouse, leading to Kalendar crashing.

The crash can be reproduced every time.

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