Bug 285627

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:
Adding my Oki B431dn network printer and then trying to set the PPD (see below) relyably chrashed the system-settings.

- Custom settings of the application:
I used the PPD downloaded from http://www.oki.co.uk/support/printer/printer-drivers/detail.aspx?prodid=tcm:122-107774&driverid=tcm:122-113452-16

The crash can be reproduced every time.

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