Bug 422901

Application: plasmashell (5.19.0)

Qt Version: 5.15.0
Frameworks Version: 5.70.0
Operating System: Linux 5.6.14-1-default x86_64
Windowing system: Wayland
Distribution: openSUSE Tumbleweed

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

Whenever I log in to Plasma, there's an icon in the system tray saying plasmashell crashed, but I'm not sure if the crash happens during login or logout.

Important: This crash message only happens when I choose the Wayland session. I'm using a NVIDIA GPU with the latest proprietary graphics driver installed, so I understand the Wayland support right now might not the best, but I'm hoping it can be improved.

Thank you!

The crash can be reproduced every time.

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