If you need more informations, please tell me what to do, while I'm able to reproduce the bug
Comment 1 Albert Astals Cid 2005-12-11 14:18:01 UTC 
Does this crash still happen if you open if from command line kpdf, that is open konsole and write kdpf pathToDocument.
Comment 2 81joe81 2005-12-11 16:09:13 UTC 
I tried to lauch it from konsole typing "kpdf" and I did same steps as before, that is I tried to open the file keeping clicked the open icon, and kpdf crashed in the same way.
I have not yet tried to open the file directly from the command line, because I think that in this way the crash will not happen: I have already opened this file at least 5 times before today.. I think the problem is related to the way I try to open it (by selecting it from the "recent files") and not to the file itself
Comment 3 Albert Astals Cid 2005-12-11 18:46:41 UTC 
The code used for opening a file via the file->open or via recent files is exactly the same.

Can you please paste the contents of the Recent Files key of your .kde/share/config/kpdfrc file?

Comment 5 81joe81 2005-12-12 10:45:06 UTC 
I've tried to open that file (REM - Losing my religion.pdf) from the normal open file icon and kpdf opened it without problems.
I've closed kpdf, restart it and trying again to open the file via the recent files icon and kpdf crashed again
Comment 6 Albert Astals Cid 2005-12-12 13:57:05 UTC 
Ok, confirmed there's some problem in recent files handling, this is more a kdelibs problem than a kdpf problem, i'll try to find a fix and if not i'll pass it to the appropiate person.
