Application that crashed: okular
Version of the application: 0.9.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-22-generic-pae i686
Distribution: Linux Mint 8 Helena - Main Edition

What I was doing when the application crashed:
I had two open documents, printed the first one which worked just fine, then sent the next one to the printer which lead to the segfault. Reopening the same document and printing it again with the exact same order of steps went just fine.

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