Bug 439086

Application: plasmashell (5.22.1)

Qt Version: 5.15.2
Frameworks Version: 5.83.0
Operating System: Linux 5.12.12-1-default x86_64
Windowing System: Wayland
Drkonqi Version: 5.22.1
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
Hope to help with these backtraces. All I did right after a clean install was set the external 4K monitor as primary, and right after Plasma shuts down unexpectedly. This happens quite frequently in the full wayland session.

- Custom settings of the application:
I only use the Breeze dark with the openSUSE dark theme option.

The reporter is unsure if this crash is reproducible.

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