Bug 314497

Application: muon-updater (1.9.80)
KDE Platform Version: 4.9.98
Qt Version: 4.8.4
Operating System: Linux 3.8.0-4-generic x86_64
Distribution: Ubuntu Raring Ringtail (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
I open the muon updater as usual and when you click on the check for updates, it spend about 30 or so seconds running the progress bar and then suddenly crashes and throws up the bug reporting assistant. Upon attempting to retry, it keeps doing it. So far the only solution has been to keep trying nearly 6-9 times of going back in and click check, go back in and click check and repeat to finally get it to a state where it pops up the system notice that there are updates, even though the actual application itself has crashed. Which is quite odd. At this point, there is no way to actually update anything without doing it manually through the terminal. I hope there is a fix pushed out soon. Muon has been VERY BUGGY lately and crashing WAY TOO MUCh for something that used to be stable and pretty reliable (at least for me).

The crash can be reproduced every time.
