Application: plasmashell (5.18.5)

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.4.0-47-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Drag&dropped advanced radio player plasmoid to desktop.

- Unusual behavior I noticed:
Plasma crashes:
The first couple of times, plasma crashed immediately after drop. Third time the plasmoid appeared but, when I went to it's setting and clicked |search|, the whole screen went black with a visible mouse cursor that didn't do anything when clicked. Rebooting does not solve the problem. I still have a black screen after rebooting and mouse still does n ot respond. KRUNNER though is accessible through alt-space.

- Custom settings of the application:
Advanced radio player plasmoid installed

The crash can be reproduced every time.

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