Hi Chris,

While we're waiting to hear back from Xerox, there's some more
debugging we can do as well.

First, if you could post for me a cairo-produced PostScript file
(produced after the bugfix described above preferably), then I'll
start pasing that PostScript file around to see if I can find other
people with access to printers which crash with this file.

Also, then the next step, (for someone with access to a crashing
printer), would be to produce as minimal a file as possible that
preserves the crash. This can be done by removing as many elements as
possible within whatever application originally produced the file. And
after that, by manually trimming the PostScript file down. We can help
with the manual-trimming process, but this will go a lot faster if
someone can do that with direct access to a printer, (to verify that
the result after trimming still crashes).

If we can get a truly minimal PostScript file out of that process,
then hopefully we'll be able to find a tweak to it to avoid the crash,
and then put a workaround into cairo for that.
