Application that crashed: ksysguard
Version of the application: 4.3.1 (KDE 4.3.1)
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
There were a 6 blocked upgrades in kpackage which had been there for a month
(probably from the kde 4.3 launchpad repo).
This happened after updating Kubuntu 9.04 using upgrade-dist in apt-get.
This was the recommended method in installing the packages.
