Bug 320957

Application: muon-updater (2.0.1)
KDE Platform Version: 4.10.3
Qt Version: 4.8.4
Operating System: Linux 3.9.2-030902-generic x86_64
Distribution: Ubuntu 13.04

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

I had told i to search for updates, and it said "Waiting" and was stuck at around 80%. So I hit cancel a couple of times, nothing happened. Then I clicked the x several times, eventually it closed with a crash message.

-- Backtrace:
Application: Muon Update Manager (muon-updater), signal: Segmentation fault
