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 2.6.31-14-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
A DVI file was auto-refreshing in Okular (it had just been modified). The symptoms are similar as those explained in bug 211765 : I had two Okular with the same file opened, but for me both could not load the file, and when I closed them they crashed. I opened the file once again afterwards without any problem.
