Bug 316641

Application: muon-updater (1.9.80)
KDE Platform Version: 4.10.1
Qt Version: 4.8.3
Operating System: Linux 3.5.0-25-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
When applying updates from 12th-May-2012, Moun crashed.  Re-opened Muon and update failed to complete but Muon did not crash.  Running updates from the command line by running

    sudo apt-get update -f

followed by

    sudo apt-get upgrade

completed the updates.

The crash does not seem to be reproducible.

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