Application that crashed: systemsettings
Version of the application: 1.0
KDE Version: 4.3.00 (KDE 4.3.0)
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:
Click on K in the low left edge, than Computer -> System Settings -> Printer configuration.
A crash is immediately reported. I have installed KDE with aptitude on a Ubuntu/Gnome system (no KUbuntu) and this is the first time I use KDE.

 -- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
