Application that crashed: okular

KDE Version: 4.2.95 (KDE 4.2.95 (KDE 4.3 RC1)) "release 139"
Qt Version: 4.5.2
Operating System: Linux 2.6.27.23-0.1-default x86_64

What I was doing when the application crashed:
I tried to print, it hung (unresponsive) after control-p with no dialog.
I restarted cups and that is when it crashed.
