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

I was deleting activities while attemplting to go down to 1 so that I could then duplicate the one remaining activity from there. When I attempted to delete the activity, Plasma crashed.

The crash can be reproduced every time.

-- Backtrace:
