That error message simply means that gs has crashed. The code block
(dvipdft is a shell script) before line 118 is:
echo "$progname: running gs" >&2
gs -r10 -dNOPAUSE -dBATCH -sDEVICE=png256 \
-sOutputFile="$tmpdir/$outBase.%d" "$outfile" || {
echo "$progname: gs failed." >&2
rm -rf $tmpdir
exit 1
}
So, this is clearly a gs bug and has nothing to do with a problem in
dvipdft. Reassigning.
There are a lot of bug fixes for ghostscript made since then. I *may*
be that your problem is solved meanwhile.

Please note that you're the only one who is able to reproduce the problem (until now). On the other hand I don't know how many people meanwhile tried to reproduce it. Further it doesn't look like a broken installation. I guess there are no similar problems for other programs on that specific box, so we can rule out hardware issues, right? Please confirm, I suggest to contact the gs maintainer then. H. -- sigmentation fault -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?

In theory we could close the bug. On the other hand dvipdft is not expected to crash, one could assume this to be an security issue. What do you think? It still occurs for me on lenny (8.62.dfsg.1-3.2lenny1), so it's at least a regular bug and I tend to agree on the potential for a security issue. It's quite likely there are automated systems (print servers come to my mind) processing user-provided postscript content with ghostscript. Unfortunately I'm busy with my diploma thesis so cannot investigate whether there might be any attack vector (DoS only probably - floating point exception doesn't sound like code execution is possible). Whatever you decide, it would be nice to get a fixed package for lenny, be it a regular bug fix update, a security update or "just" a backport.
