Bug 510805

Application: plasmashell (6.4.5)

ApplicationNotResponding [ANR]: false
Qt Version: 6.9.2
Frameworks Version: 6.18.0
Operating System: Linux 6.14.0-33-generic x86_64
Windowing System: X11
Distribution: KDE neon User Edition
DrKonqi: 6.4.5 [CoredumpBackend]

-- Information about the crash:
On some bootups, plasmashell will crash shortly after displaying the desktop and panel, and will nearly always crash again upon restart. Curiously, this doesn't happen on all bootups - on good bootups, plasmashell will keep running first time.

This happens regardless of whether X11 or Wayland is used. This backtrace is from X11.

The system is a fairly old KDE Neon install.

The crash can be reproduced sometimes.
