Bug 293904

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 3.0.0-12-generic i686
Distribution: Ubuntu 11.10

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

trying to install updates to the new kubuntu install
every time the system would report that there is another process in the background using the same app.

The crash can be reproduced every time.

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