Application: plasmashell (5.15.4)

Qt Version: 5.15.0
Frameworks Version: 5.57.0
Operating System: Linux 5.1.15-desktop-1bP x86_64
Distribution: "blackPanther OS v18.1 (Renegade)"

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

1.) Clicked to settings button on any plasma panel (the plasmoids settings button working fine) 
2.) Remove any plasmoid from desktop (add any new plasmoid working fine, can't remove)

The crash can be reproduced every time.

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