Bug 463666

Application: plasmashell (5.26.4)

Qt Version: 5.15.7
Frameworks Version: 5.101.0
Operating System: Linux 6.1.1-zen1-1-zen x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 5.26.4 [KCrashBackend]

-- Information about the crash:
Custom window manager used, launched with systemd (user).
Kwin service is masked.
latte-dock is used.

Crashes at startup but I only see the notification. I click "restart app" and it eventually works.
If there is a window opened too soon (before it starts correctly) it crashes non stop (at each "restart" from the notification).

This might very well be related to my window manager (a heavily modified dwm). Any suggestion on what to look for in it would be appreciated :)

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
