Bug 515644

Application: plasmashell (6.6.80)
 (Compiled from sources)
ApplicationNotResponding [ANR]: false
Qt Version: 6.10.2
Frameworks Version: 6.23.0
Operating System: Linux 6.18.7-zen1-1-zen x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 6.5.5 [CoredumpBackend]

-- Information about the crash:
Whenever I do kwin_wayland --replace to restart the compositor, plasmashell triggers a crash instead of a sudden kill (sigkill).

However, it should not wait for it to close gracefully as the reason to restart kwin or plasmashell might be due to behavior problems such as freezing, which would defeat the purpose of restarting, but it should not be registered as a crash.

The crash can be reproduced sometimes.
