Bug 289394

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 x86_64
Distribution: Ubuntu 11.10

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

I had just installed a Workcenter 7665 using the PPD located at 
http://ecee.colorado.edu/~ecehelp/src/Xerox_drivers_201008/Linux/Xerox-WorkCentre-7655-7665-7675.ppd

When I pressed "Print Test Page" systems settings crashed.  The first time I skipped the bug reporting dialog.  I reopened and tried again and it did not crash on pressing print test page.  However, there was an error in the tray selection so the test page was not printed. I changed the tray selection, and again, system settings crashed when I pressed print test page.

Kubuntu 11.10 64bit  (Standard, up-to-date install)

The crash can be reproduced some of the time.

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