Application: plasmashell (5.23.90)

Qt Version: 5.15.3
Frameworks Version: 5.91.0
Operating System: Linux 5.13.0-28-generic x86_64
Windowing System: Wayland
Distribution: Custom Live CD
DrKonqi: 5.23.90 [CoredumpBackend]

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

logging in upon boot

- Unusual behavior I noticed:

repeating segfaults under different plasmashell PIDs over and over and over again. Wallpaper keeps blanking out and returning, possibly due to new process spawning?

The reporter is unsure if this crash is reproducible.

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