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-pae i686
Distribution: Ubuntu 11.10

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

trying to get the Lexmark software / driver working - as I follow threads online the .deb package has yet to work,  printer config has tried to get it working w/o the lexmark software but it crashed on the test print part

The crash can be reproduced every time.

-- Backtrace:
