Application that crashed: okular
Version of the application: 0.9.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.30-2-686 i686
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
In okular's print dialog: I edited the "advanced" tab of printer properties for printer A, closed it, changed to a  different printer, and went to its advanced printer properties, and then okular crashed. Standby, I will see if I can reproduce this soon.

 -- Backtrace:
