Application: systemsettings (1.0)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

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

When providing a ppd file for adding a new 	printer, it crashes everytime.

The crash can be reproduced every time.

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