Bug 326253

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:
I've just installed the new Kubuntu 13.10, and tried to update the system. To do so I opened the Muon Update and It's just crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: Muon Update Manager (muon-updater), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
