Application: plasmashell (5.22.4)

Qt Version: 5.15.2
Frameworks Version: 5.84.0
Operating System: Linux 4.4.180-1.g7cfa20a-default x86_64
Windowing System: X11
Drkonqi Version: 5.22.4
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
Added a webslice plasmoid to an activity
- Unusual behavior I noticed:
plasmashell crashes repeatedly closing and crashing on restarting again
- Custom settings of the application:
Webslice plasmoid installed; opensuse factory qt5/kf5/plasma packages

The reporter is unsure if this crash is reproducible.

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