Bug 278113

Application: muon-updater (1.1.85 "Caustic Carrionite")
KDE Platform Version: 4.6.90 (4.7 RC1)
Qt Version: 4.7.3
Operating System: Linux 3.0.0-5-generic x86_64
Distribution: Ubuntu oneiric (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
I had just enabled the Partner Repositories, it performed the database update and found some updates.  I then clicked on the update icon to then see the crash dialog.  The update icon was still there, so I clicked it again to get the same crash.  However, the third click didn't result in it crashing.

The crash can be reproduced every time.

-- Backtrace:
Application: Muon Update Manager (muon-updater), signal: Segmentation fault
