  Target Milestone: ---

Application: korganizer (5.21.3 (22.08.3))

Qt Version: 5.15.6
Frameworks Version: 5.102.0
Operating System: Linux 5.19.0-31-generic x86_64
Windowing System: X11
Distribution: Ubuntu 22.10

-- Information about the crash:
I had added school holidays from Apr-3 to Apr-14 (multi-day event). When I
wanted to extend it to also cover the last weekend (Apr-15+16), I grabbed the
end of the event and moved the mouse to the right. I didn't stop it early
enough and somehow exited the korganizer window. In that instant korganizer
crashed. I could reproduce it easily. Also, when I prolong the event and stop
moving the mouse at the correct time, everything works as designed.

The crash can be reproduced every time.

-- Backtrace:
Application: KOrganizer (korganizer), signal: Segmentation fault
