Bug 451605

Application: plasmashell (5.24.3)

Qt Version: 5.15.3
Frameworks Version: 5.91.0
Operating System: Linux 5.16.14-arch1-1 x86_64
Windowing System: X11
Distribution: Arch Linux
DrKonqi: 5.24.3 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
Searching in Clipboard tray widget, then deleting the search terms with backspace or delete keys.
This crash has occured more than thrice since 5.24.(probably 0?) and a few times plasma did not authomatically restart.

Incidentally (not sure if possibly related or a different bug) it occures often when editing/searching in clipboard widget gives hits on some long text excercepts/urls which then become visually clamped and glitchy, and this glitchines persists for some time even without any active searches in Clipboard widget's search bar.

The crash can be reproduced sometimes.

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