Bug 326252

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 x86_64
Distribution: Ubuntu 13.10

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

After updating kubuntu 13.04 to 13.10 muon-installer crashes. It runs for 2 seconds

I. kubuntu 13.04 used for some time with custom apps installed, then updated to 13.10
II. clean kubuntu 13.04 updated to 13.10 just after installing OS

In both cases Muon Software Center crashes after updating to 13.10 (Muon Discover and Muon Package Manager works fine).

The crash can be reproduced every time.

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