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.

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

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
