Comment 1 Ladislav Nesnera 2008-02-25 11:05:26 UTC 
Is there some way to upload problematic file?
Comment 2 Pino Toscano 2008-02-25 11:17:20 UTC 
Yes, add a new attachment to the bug report (how big is the document?)

Also, please provide a more useful backtrace, as explained in http://techbase.kde.org/index.php?title=Development/Tutorials/Debugging/How_to_create_useful_crash_reports

Possibly, trying a newer KPDF version would be also a good thing...
Comment 3 Ladislav Nesnera 2008-02-26 12:33:49 UTC 
Problematic pdf is available at http://nesnera.webgarden.cz/file/6868759
Comment 4 Pino Toscano 2008-02-26 12:47:46 UTC 
Can confirm the crash with KPDF 0.5.8 (KDE 3.5.8):

Comment 5 Pino Toscano 2008-02-26 12:49:05 UTC 
... but I can confirm also that with KPDF 0.5.9 (KDE 3.5.9) it works (no crashes).
Comment 6 Albert Astals Cid 2008-02-26 19:36:35 UTC 
0.5.9 does not crash here either but i can see a wrong write with valgrind
