Application: plasmashell (5.21.3)

Qt Version: 5.15.2
Frameworks Version: 5.80.0
Operating System: Linux 5.11.10-051110-generic x86_64
Windowing System: X11
Drkonqi Version: 5.21.3
Distribution: KDE neon User Edition 5.21

-- Information about the crash:
- What I was doing when the application crashed:
Took a screenshot for the second time (into clipboard), as the first time the screenshot was not available in clipboard for unknown reasons (this happens frequently, usually without a crash).

- Unusual behavior I noticed:
Plasmashell seems to have restarted, the screenshot thumbnail took very long to load.


It seems to be mildly related to https://bugs.kde.org/show_bug.cgi?id=430862, yet yesterday's kio update fixed the described issue pattern, while this issue is (still) sometimes(!) reproducible with the new update.

The crash can be reproduced sometimes.
