Problems Setting Drawers in .emacs

[Ian Barton <lists@manor-farm.org>]

Recently I have noticed a problem setting up Drawers. In my .emacs I have:

(add-to-list 'load-path "~/.emacs.d/src/lisp")
(add-to-list 'load-path "~/.emacs.d/src/org-mode/contrib/lisp")
(require 'org-install)
(require 'org-babel-init)
(org-babel-load-file "~/.emacs.d/blacky.org")

In ~/.emacs.d/blacky.el I have:

;; Define some default drawers.
(setq org-drawers (quote ("PROPERTIES" "SETUP")))

However, PROPERTIES and SETUP aren't recognised as drawers in my org 
files. They don't close and open using tab and the fontification of them 
indicated that org isn't recognising them as drawers.

If I define a drawer in my org file like:

#+DRAWERS: NOTES

this works correctly. Clearly something has got messed up in my setup, 
but I can't work out what it might be.  have moved the org-drawers 
definition near to the top of blacky.el to no effect.

I have also tried deleting my git repo and doing a new checkout.

Before I take the axe to my org configuration and start chopping bits 
off to find out where the problem is, can anyone suggest any reason why 
this might happen?

Ian.
