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:

After a new installation of 11.10 I had to add my printer again. I did that from the vendor list (I DID NOT SELECT NOT "IPP"), chose the correct type, added all neccessary information/settings and at the end I clicked on "Testpage". A small window showed "Print job  #1 added to list" (or something like this and got the crash immediately. 

After restarting the application I tried the Testpage again but with the same result. No testpage has been printed at all

The crash can be reproduced every time.

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