Bug 298175

Application: systemsettings (1.0)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-17-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Finished installing Canon Pixma MP620.
Pushed the "print test page" button.
A dialog informing me that the page was sent to the printer appears.
Pushed the "ok" button.

Configuration app immediately crashes. The test page is added to the print queue, but not printed.

The crash can be reproduced every time.

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