Thanks Dan,

Your fix works for me :).

I'm confused about _why_ I'm getting these errors though - I was
expecting fontification only to apply to #+begin_src blocks and I'm only
using a few languages in that document (sh, org, emacs-lisp, ditaa, and dot).

Unless it's picking up on the begin_src in the following text

,----
| I use this to create =#+begin_*= blocks like 
| - =#+begin_example=
| - =#+begin_ditaa=
| - =#+begin_dot=
| - =#+begin_src=
| - etc.
`----

I wasn't able to determine the source line of the problem from the stack
dump information.  Is there any way to determine what part of the
document is causing this (other than manually bisecting and exporting
with missing sections) ?

Regards,
Bernt
