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

I was trying to search for available activity templates. When I hit the get new templates button and pushed the sort by rated radio button before the list appeared, the window crashed.
Happened twice in a row.

The crash can be reproduced every time.

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