Bug 329550

Application: muon-discover (2.1.2)
KDE Platform Version: 4.11.3
Qt Version: 4.8.4
Operating System: Linux 3.11.0-15-generic i686
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
I had just downloaded OpenShot Video Editir via Muon Discover and the install process was initialized. I tried to switch to the Openshot window when Discover crashed.
Thanks and Happy New Year all.
Bren

-- Backtrace:
Application: Muon Discover (muon-discover), signal: Segmentation fault
