Application: plasmashell (5.22.3)

Qt Version: 5.15.3
Frameworks Version: 5.84.0
Operating System: Linux 5.8.0-59-generic x86_64
Windowing System: Wayland
Drkonqi Version: 5.22.3
Distribution: KDE neon User Edition 5.22

-- Information about the crash:
- What I was doing when the application crashed:
Sometimes when Intelij Idea 2020 Community Edition IDE is open the entire Wayland session crashes (all open applications, elisa, K3B, Firefox, etc..) are killed as part of the restart.

The behavoiur doesn't seem tied to resource usage, idea wasn't building/doing anything but Elisa silently crashed mid song. I went to open Elisa and the entire Wayland desktop restarted.


- Unusual behavior I noticed:
Firefox and Intelij Idea 2020 Community Edition don't seem to consistently support copy/paste. Sometimes keyboard shortcuts work (sometimes not), sometimes using the context menu works (sometimes not)

The crash can be reproduced sometimes.

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