Bug 428678

Application: plasmashell (5.20.2)

Qt Version: 5.15.1
Frameworks Version: 5.75.0
Operating System: Linux 5.9.1-1-default x86_64
Windowing system: Wayland
Distribution: "openSUSE Tumbleweed"

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

login to new plasma wayland session
this always happens when I log in. Plasma then restarts and works as expected

The crash can be reproduced every time.

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