Application: okular (0.14.3)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-38-generic x86_64
Distribution: Ubuntu 12.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I wanted to print a certain pdf-document a second time. I pressed Ctrl-P for that. The program did not hang, it just closed immediately.

The crash can be reproduced some of the time.

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