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 i686
Distribution: Ubuntu 13.10

-- Information about the crash:
Muon is behaving strangely.  

1. It tells me that there is an update but when I open Muon, I am told no updates are available. because of this I use the CLI to update Kubuntu.
2. Muon dropdown box (lower left corner) - every time I attempt to select a listed option, Muon crashes. 

It looks like similar Muon issues have been reported, but I did not see any one that included use of the dropdown box to select an option.

Thank you for your work on this product! And thank you for improving the bug reporting system.

The crash can be reproduced every time.
