Well, there are glitches :) notably the fact that Cairo itself doesn't
quite do everything we need it to. Adrian Johnson wants to create a PDF
specific library that uses Cairo for its drawing but that knows about
the rest of the PDF spec (as there are a number of PDF want-to-haves
that just don't belong in Cairo, and won't get there, unfortunately).
Needless to say that's a year+ away, but I'm hoping to support him as he
goes.

That said, Cairo 1.9 is a *significant* improvement over 1.8 in a lotof
areas we touch using PdfSurface.

So that's actually one of the problems; right now Cairo converts it to a
bitmap or so, rather than just embedding the damn (ie) jpg. That's fixed
in 1.10 by the addition of a setMimeType() API. But we don't have that
yet.

So, if you could post on a server or pastebin somewhere the VM crash
dump you get from the JVM, that might help. 

It might help people on the list if they could see some code, too. Hard
to imagine what context you have that led to a crash there.
