Bug 321818

Application: muon-updater (2.0.65)
KDE Platform Version: 4.10.90
Qt Version: 4.8.4
Operating System: Linux 3.9.0-6-generic i686
Distribution: Ubuntu Saucy Salamander (development branch)

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

During an update with the muon updater, KDE crashed without any notice. I got a message 'A new version of Kubuntu is available" which is funny because I am using Kubuntu 13.10 Saucy alpha 1 ...

-- Backtrace:
Application: Gestionnaire de mises à jour Muon (muon-updater), signal: Aborted
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
