It's hitting an assertion failure during syntax-propertizing.  The
problem seems to be that the parse-partial-sexp call in
sgml--syntax-propertize-ppss isn't using the right syntax table.  I
wonder why it doesn't happen for sgml-mode though (as far I can tell).
Stefan, any thoughts about that?

Patch below fixes it, but it might just be papering over another
problem.
