Application that crashed: okular
Version of the application: 0.9.4
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.9-174.fc12.x86_64 x86_64
Distribution: "Fedora release 12 (Constantine)"

What I was doing when the application crashed:
Using okular as my PDF viewer within Kile, I have trouble when I set it to use the '--unique' switch. It crashes whenever it tries to load a document that is already open. I cannot replicate this from the command-line.
