Comment 1 Albert Astals Cid 2009-10-19 00:53:29 UTC 
Can you please attach one of those files?
Comment 2 Kevin 2009-10-19 06:22:20 UTC 
Created attachment 37659 [details]
open okular with a few copies of this, and it will crash

btw, the .ps file isn't rendered correctly either (assuming ps2pdf is correct)
Comment 3 Albert Astals Cid 2009-10-19 21:06:40 UTC 
Here it works, that is, this file named foo.pdf, is detected as a ps and is opened, but i agree it seems to be rendered incorrectly.

The thing is that the test application renders the file fine, so definetely there is something wrong in our code
Comment 4 Kevin 2009-10-19 23:09:25 UTC 
i have to open at least 4 copies for okular to crash
Comment 5 Albert Astals Cid 2009-10-21 00:53:09 UTC 
You mean opening a file is ok, but opening 4 different instances of the same file makes okular crash? Or are you using embedding of okular part inside konqueror?
Comment 6 Kevin 2009-10-21 05:41:15 UTC 
yes, so when I make 4 copies of the attatched file

$ ls
1.ps 2.ps 3.ps 4.ps
$ okular *

then okular crashes but

okular 1.ps

wouldn't crash okular
Comment 7 Albert Astals Cid 2009-10-23 00:38:28 UTC 
Should be fixed in next okular version, thanks for the report
