Application that crashed: okular
Version of the application: 0.8.90

Qt Version: 4.5.0
Operating System: Linux 2.6.28-13-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
i added a review to the document then used file/save as to make sure the changes had been saved.

save as was to overwrite the old one with the same name. i confirmed.

next it appeared as if okular did not have any documents opened. this was then followed by the crash and this report assistant.
