The /invalidfileaccess error message seems to suggest that something
with respect to file handling has changed in Ghostscript.  (I haven't
checked the Ghostscript documentation with respect to that yet.)

We've had a bug report in August which was related to file handling of
Ghostscript: http://article.gmane.org/gmane.emacs.auctex.general/3837

It looked like the openSUSE maintainers added a /PermitFileReading
statement to the gs call.  Perhaps we need to add such a statement as
well in AUCTeX proper?  I'll check this once Ghostscript 9.00 hits
Debian/sid.  If you are interested in acting as a guinea pig I can also
check the Ghostscript documentation sooner and try to come up with a
patch without reproducing the error myself.
