-- Information about the crash:
This is really easy to reproduce, with a remote nextcloud agenda, set kalendar
in month view (maybe other view have the same result), select an event then
clic delete (keyboard del) as soon as the event is going away the crash is
present.

This (mis)behavior appear once my plasma setup was moved to qt6/wayland (was
working well before with qt5/X11)

The crash can be reproduced every time.

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