Bug 326426

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 wanted to deinstall "wbar". I opened Muon, clicked on "installed software" and it crashed.
It crasehd a 3rd and 4th time too

- Unusual behavior I noticed:
2 days ago I had Kubuntu 13.04, it worked without problems. After upgrading to 13.10, "wbar" (some kind of sidebar) started with kubuntu. It didn´t let me open it´s preferences or deactivate, I had to kill the process over "Gnome Systemwatcher" (sorry, got a german Kubuntu, trying to translate :).
That´s why i wanted to deinstall "wbar"

- Custom settings of the application:
"wbar" may not be the reason, but it´s the reason why I noticed the error.
"Muon Packetmanager" and "Moun Actualisationmanager" still works, Kubuntu is up to date.

Sorry if I´m confusing you with bad english or irrelevant details, I´m a linux-noob :)
