:-)
there are minor issues, like the fact the scroll bar aren't framed,
so it looks a bit strange, and that you didn't set a minimum window
size..

it doesn't seem to be a problem of PDF -- all the pdf I tested crashed
(even my own made with LaTeX)

Well, I called gs by hand, following the same approach : cat /tmp/cvnico-en.pdf 
| gs -dNOPAUSE -sOutputFile=/tmp/nico/gs15335_1_%d.tiff  -r144x144 
-sDEVICE=tiff24nc -dTextAlphaBits=4 -dQUIET -dSAFER -

... and it works ! so it seems to be a problem with NSTask here ...
I have a quite recent cvs version of GNUstep, but is something changed
recently on NSTask ?
I'll try to find what's the problem.

yes, eventually let the user modify the parameters given to gs in an
"advanced user" preference ;-)
