-- Information about the crash:
- What I was doing when the application crashed:
after upgrade to kde 4.7.4 and login back to my session, I went in system settings and then to printer configuration just to check settings, changing nothing.
I went back to system settings, then close system settings window => crash

-- Backtrace:
Application: Configuration du système (systemsettings), signal: Segmentation fault
