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 2.6.31-17-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I was reading, reviewing and 'editing' a pdf file.

I entered several edits (inline notes, notes, green pen, highlight) and refreshed/reloaded (F5) the document.
At a certain point, I tried to enter a new highlight and at the moment I pressed "5" (shortcut for highlight) okular crashed.

Regards,
gp
