Application: muon (1.1.80 "Caustic Carrionite")
KDE Platform Version: 4.6.4 (4.6.4)
Qt Version: 4.7.3
Operating System: Linux 3.0-1-generic i686
Distribution: Ubuntu oneiric (development branch)

-- Information about the crash:
Started Muon Package Manager for the first time and while loading the Packagelist it crashed. Did not crash again when starting again afterwards (tried ~ 5 times)

The crash does not seem to be reproducible.

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