Bug 256985

Application: kpackagekitsmarticon (0.6.2)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed: Firefox is running, but this seems to be a new fault, as it has not happened before, but now seems to be tied with Firefox. Kget was recently installed, but I have no idea whether this could cause a problem. Medibuntu repository was added.

- Custom settings of the application: Not much, except that a 'persona' (Firefox customization) is present. The KDE installation is from Kubuntu 10.10 distribution, and most of it is quite standard. Medibuntu repositeries were added however, again I am not sure whether this may have caused an issue.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KPackageKit (kpackagekitsmarticon), signal: Segmentation fault
