[O] completion <M-TAB> / :CREATED: property issue

[Francis J. Monari, Esquire]

completion <M-TAB> / :CREATED: property issue

what i saw: a list of possible drawers
what i expected: a list of possible properties

In the following outline: using completion after the 1st colon / open
property location presents a list of possible properties; using
completion after the 2nd colon / open property location presents a list
of possible drawers.  I believe that the issue is caused by the
":CREATED:" property.

* test
  :PROPERTIES:
  :
  :CREATED:  [2015-04-23 Thu 12:41]
  :
  :END:
========

I am able to reproduce this issue in a 'fresh' file with the outline
above.  I am using:

Window 7 Home Premium Version 6.1 (Build 7601: Service Pack 1).  It is
my habit to run Windows Update.

(emacs-version) "GNU Emacs 24.4.1 (i686-pc-mingw32)  of 2014-10-24 on
LEG570"
(org-version) "8.2.10" 20150420.

(require 'org-expiry)
;;;org-expiry - variables
(setq org-expiry-confirm-flag t)
(setq org-expiry-inactive-timestamps t)
;;;org-expiry
(org-expiry-insinuate)

I am able to reproduce this issue in a minimal setup runemacs -Q with
one difference: Using completion at the 2nd colon inserts the beginning
of a new property drawer ":PROPERTIES:".  I do not see this difference
as being significant (a drawer instead of a property is offered).

I have not found this issue on the list of open or archived bugs.

I realize that this is an add-on and the answer might be: "This issue is
somebody elses' problem."

Any help or a pointer as to where a correction might lie would be
greatly appreciated.

Thank you,

Frank.
