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:
- What I was doing when the application crashed:

- i rebooted my laptop
- logged in and did not nothing
- waited for the muon updater to kick in and warn me that new updates were available
- clicked the updater in the taskbar
- updater opened
- no updates were available (red icon in updater)
- i clicked update and the application crashed

The crash can be reproduced every time.
