Bug 300492

Application: okular (0.13.3)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-19-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: 

I was working with kile and compiled my dvi. Okular tried to reload the dvi file but got stuck. I tried to quit by clicking the close window button and then Okular crashed. 


- Custom settings of the application: 

I use the latex source specials in okular to open a given place in the dvi file in kile. (Hence I also open the file in okular using forwarddvi in kile after having compiled the source code using srcltx.) I guess none of this is connected to the error, but I put it here for completeness.

-General remark:

I file a duplicate of my own bug report #300275 , because this crash happened on my Ubuntu Oneiric install, whereas the duplicate was in Ubuntu Precise. I can perhaps provide more information on the present report but not on the duplicate. (Close the duplicate?)

The crash can be reproduced some of the time.
