Bug 446248

Application: plasmashell (5.23.3)

Qt Version: 5.15.3
Frameworks Version: 5.88.0
Operating System: Linux 5.11.0-40-generic x86_64
Windowing System: X11
Distribution: KDE neon User - Plasma 25th Anniversary Edition
DrKonqi: 5.23.3 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:

I right clicked both partitions on the USB stick and selected eject. Then removed the stick (it is the plasma user edition install media). Then came the crash.

The crash can be reproduced sometimes.

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