Description Giovanni Venturi 2006-10-10 22:20:30 UTC 
Version:           0.5.5 (using KDE 3.5.5, compiled sources)
Compiler:          gcc version 3.4.6
OS:                Linux (i686) release 2.6.17.13

I compiled KPDF from kdegraphics SVN trunk 3.5 on the 10th October and I get always crash opening the attached PDF file.

Using host libthread_db library "/lib/tls/libthread_db.so.1".
[Thread debugging using libthread_db enabled]

Comment 2 Albert Astals Cid 2006-10-10 22:39:59 UTC 
Works here, please go to performace tab, uncheck the background generation option, make it crash and put the backtrace again, it should be more useful than the one you posted.

this is the correct pdf file that make to crash kpdf

I disabled as you sayed but with the correct PDF file and I get no debug output
and it chrashed the same.

SVN commit 594669 by aacid:

Painting an image of 0x0 does not seem right and is making it crash
With this code we get roughly the same output than acroread, this basically means your pdf is broken
