Application: muon-updater (2.0.65)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
I was doing nothing important, I just clicked on the update icon in system tray, waited for Muon to open and then it told me there were no updates (but it's wrong, as it's not the first time this happens: if I open a terminal and type apt-get upgrade, it'll show several updates and it'll go ahead and update smoothly). Anyway, after clicking the close button Muon crashed.
- Unusual behavior I noticed:
After the upgrading Kubuntu to version 13.10, some KDE applications are not working properly.

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