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

I opened Muon. In the background I had Amarok, Firefox and Akregator running. Muon crashed with no explanation or error - just a segfault.

The crash can be reproduced every time.

-- Backtrace:
Application: Muon Software Centre (muon-installer), signal: Segmentation fault
