Application: muon-installer (2.0.1)
KDE Platform Version: 4.10.3
Qt Version: 4.8.4
Operating System: Linux 3.8.0-23-generic x86_64
Distribution: Ubuntu 13.04

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

I was attempting to install "compiz icon" via Muon Software Manager and after having clicked "install" and entered credentials of privileged user I noticed that the installation had appeared to stall with no progress having been made so I decided to cancel and try again. When I clicked on the icon with red circle with a line through it then attempted to close Muon it crashed and burnt.

The crash can be reproduced sometimes.

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