Bug 294327

Application: muon-installer (1.2.1 "Caustic Carrionite")
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

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

I was uninstalling Wine.  There were three Wine packages that I had to uninstall.  I pressed "Remove" on all of them, and when the final one finished uninstalling, the application crashed.  This has never happened before when I was uninstalling anything.

The crash does not seem to be reproducible.

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