Other information:
I know this is a corrupt document. But Acrobat Reader doesn't crash : it just
tells me "This file cannot be opened because it has no pages".
Unfortunatly, "my" users generates a lot of such files and it's not always easy
to know if it's a real crash or a corrupt document.
As far as I know, evince has always crashed with this file (0.2x, 0.3.x, 0.3.3)
