Hi Carsten,
This appears to be an issue in the HEAD (as of two weeks ago) of the
Emacs git repository. I was able to get around this issue (and a couple
of other font-lock related issues) by stepping back to an older version
of Emacs (tag EMACS_23_2 in the git repository).
I haven't tried to go back to the Emacs development HEAD, but I assume
that they'll take care of this issue sooner or later, either way it's
not a problem with any of the code in Org-mode.
Best -- Eric
