Application that crashed: okular
Version of the application: 0.9
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.30.5-43.fc11.i686.PAE i686
Distribution: "Fedora release 11 (Leonidas)"

What I was doing when the application crashed:
A dvi file opened with okular is several time modified (latex compilation) and each time okular recharges the file in order to show the new content. After a lot of modifications (>50), okular crashed.

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