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

clicked on the activities button in the taskbar and then went to add widgets and it crashes but doesn't crash if you add them any other way

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
