Description Kai 2021-11-17 15:09:29 UTC 
Application: plasmashell (5.23.3)

Qt Version: 5.15.3

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 just chaneged the desktop global theme, and boom, plasma just crashed

- Unusual behavior I noticed: animated elements wernt... well, animated, loading in to an aplication, taskbar just shows practicly just an image on top of the application icon, the splash screen had no animation, and ended shortly in to loading plasma

The reporter is unsure if this crash is reproducible.

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