P.S. this is becoming another subject for a FAQ which should cover both
org-special-blocks.el
Remember to cover the basics, that is, what you expected to happen and
what in fact did happen. You don't know how to make a good report? See
http://orgmode.org/manual/Feedback.html#Feedback
Your bug report will be posted to the Org-mode mailing list.
