Bug 459607

Application: plasmashell (5.25.5)

Qt Version: 5.15.5
Frameworks Version: 5.98.0
Operating System: Linux 5.19.9-200.fc36.x86_64 x86_64
Windowing System: X11
Distribution: Fedora Linux 36 (Workstation Edition)
DrKonqi: 5.25.5 [KCrashBackend]

-- Information about the crash:
The Desktop turns black, no tools or any way to configure sound?

If I close down Firefox, and the site with the video/sound, I can't use the box, I have to reboot.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Bus error
