Trace while opening the file

Bug forwarded from Evince: http://bugzilla.gnome.org/show_bug.cgi?id=532767

"Evince crashed (and so does Okular and Foxit Reader) when opening one of the
files from this page:

http://www.tu-harburg.de/parallel/imbi2/vorlesung.html

One file that crashes:

http://www.tu-harburg.de/parallel/imbi2/skripten/2/kapitel2.pdf

Acrobat Reader opens them fine, but who wants to use that? :)

I'll attach a trace."

I got a similar trace with glib demo:

Program received signal SIGSEGV, Segmentation fault.
