KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.30-2-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
can reproduce the crash all the time. Python is up to date. I decided to configure ands adjust the prionter though localhost:631, the old buddy worked fine.

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