Application: muon-installer (2.0.65)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic i686
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:I upgraded from Kubuntu 13.04 to 13.10. After the restart when the upgrade process was completed, every time I try to open Muon Software center the application Crashes. I have noticed in Kubuntu 13.10 that there is Muan discovery center, does this have the same function as Muan software center. If so can I uninstall Muan Software center?

The crash can be reproduced every time.

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