Bug 331055

Application: muon (2.1.2)
KDE Platform Version: 4.12.1
Qt Version: 4.8.6
Operating System: Linux 3.13.0-031300-generic x86_64
Distribution: Ubuntu 13.10

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

I added debian-multimedia repositories in order to have some codecs which I needed. A newer (latest) version of VLC and some other programs was available on that repositories, therefore I did a full upgrade.
The software then told me it was not possible because of some broken dependencies. 
I decided to select for remove the broken packages so that whatever was not related to it could upgrade,
muon started to download packages but at the time of applying changes it crashed. I would have expected that it would have given an error that the changes could not be applied

The crash can be reproduced every time.

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