Bug 287452

Application: systemsettings (1.0)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:

I had opened systemsettings and installed an usb printer. Everything worked o.k., no crash after adding printer as so often...
Then I closed systemsettings (right upper corner) and it crashed.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Systemeinstellungen (systemsettings), signal: Segmentation fault
