Sentry Crash Report:

Description twopt0 2021-06-05 20:13:20 UTC 
Application: plasmashell (5.21.5)

Qt Version: 5.15.3
Frameworks Version: 5.82.0
Operating System: Linux 5.4.0-74-generic x86_64
Windowing System: X11
Drkonqi Version: 5.21.5

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

On rare occasion, Plasma crashes and restarts when I press ctrl-a to select all icons on the desktop. After Plasma has restarted itself, ctrl-a behaves as expected and all icons are selected.

The crash does not seem to be reproducible.

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