Application: okular (0.16.2)
KDE Platform Version: 4.10.2 "release 1"
Qt Version: 4.8.4
Operating System: Linux 3.7.10-1.4-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Steps to reproduce:
1. Print a document
2. In the printing dialog, select "Properties" and change to "Advanced" tab
3. Change any option and press cancel
4. Press "Properties" and "Cancel" again and repeat this. The third time you press "Properties" it will crash

- Unusual behavior I noticed:
If you change the option it will immediately be reset in the list if you press "OK" or click anywhere else. If you change the option and press "Cancel", the new setting will be shown the next time you click "Properties" again, though.

Additional info:
Not only happens with Okular, so I think it's a bug in the printing dialog

The crash can be reproduced every time.

-- Backtrace:
Application: Okular (okular), signal: Segmentation fault
