Application: muon (1.2.1 "Caustic Carrionite")
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
The new Kubuntu 11.10 application upgrader (now called apper?) notified from the panel that upgrades were available, so I clicked it and let it upgrade (ubufox or something or other).  Meanwhile I wanted to check on some library, so I ran Muon Package Manager  (the new KPackageKit replacement?) from the Kickoff launcher.  Muon immediately crashed, and here I am.

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