Bug 328931

Application: muon-updater (2.1.1)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-14-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
Opened Muon updater, clicked 'More' button > Advanced > Configure Software sources. Entered password. Checked 'Source Code' box on Kubuntu Software tab. Checked 'Pre-released updates' box on Updates tab. Clicked Close button. Muon went to reload repository information and crashed (didn't happen to notice if it was right away or a few seconds after starting to refresh the software lists).

- Custom settings of the application:

Software sources > Kubuntu Software > Source Code box checked
Software sources > Updates > Pre-released updates box checked

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