Summary: Crash when changing advanced printer settings and canceling in printer dialog
Product: [Applications] okular Reporter: Mister Ypsilon <mrypsilons>

Description Mister Ypsilon 2013-05-07 16:59:30 UTC 
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

Comment 1 Albert Astals Cid 2013-05-07 20:54:41 UTC 
The crash is deep inside Qt printing dialog, not much we can do here really. There are various reports upstream at the Qt bug site, unfortunately seems there's not much action around them :-/

New crash information added by DrKonqi

okular (0.14.3) on KDE Platform 4.8.5 (4.8.5) using Qt 4.8.1

- What I was doing when the application crashed:

I was trying to find out how to change a printer option when Ocular crashed.
Ubuntu 12.04
Ocular parameters not modified, it was my first use of Ocular.

The only difference is that I do not have this problem in other programs that use the Epson Stylus NX305 printer.

I used another document viewer to print out the .PDF document without any problems.
