Bug 416116

Application: plasmashell (5.17.5)

Qt Version: 5.13.2
Frameworks Version: 5.65.0
Operating System: Linux 5.0.0-37-generic x86_64
Distribution: KDE neon User Edition 5.17

-- Information about the crash:
- What I was doing when the application crashed:
Logging in with wayland

- Unusual behavior I noticed:
The wallpaper turning grey

- I logged out and logged back in multiple times, this seems to fix it.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
