Comment 1 Dario Andres 2009-09-09 18:04:16 UTC 
- Does Okular crashes if you repeat the situation ? - If it does, can you try switching your widget style from Oxygen to other one (like Plastique) and re-test ?
It seems to be a Oxygen and/or Qt painting bug; related to a treeview.

Thanks

Changed to plastique and when opening file from in firefox, this crash happened.

Comment 4 Dario Andres 2009-09-16 22:03:35 UTC 
Mh, the three backtraces are different.. The second one seems to be related to kdelibs and the third one to Poppler/freetype.

- Did you get all the three crashes with the same steps ?

Thanks
Comment 5 Tomas Vavra 2009-09-17 09:01:56 UTC 
Another one to help find out why.

Comment 6 Tomas Vavra 2009-09-17 09:02:37 UTC

just posted another dump.

Have a nice day
