Application: plasmashell (5.22.3)

Qt Version: 5.15.3
Frameworks Version: 5.83.0
Operating System: Linux 5.8.0-59-generic x86_64
Windowing System: Wayland
Drkonqi Version: 5.22.3
Distribution: KDE neon User Edition 5.22

-- Information about the crash:
- What I was doing when the application crashed:
I think that the crash occured after my (only) monitor went into standby mode.

I am not sure this always happens. I've also seen qt apps (konsole) freeze. What happens
reliably is that the screen locker crashes when monitor goes to standby mode.

The crash can be reproduced sometimes.

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