I was trying to archive a TODO item and org-mode locked up.  I've
traced it down to org-get-tags-at which never returns. Below is a
stack trace with the "looping" portion marked.

--- End Loop
  org-outline-level()
  outline-up-heading(1 t)
  org-up-heading-all(1)
--- Loop
  org-get-tags-at()
  org-set-tags(nil t)
  org-promote()
  org-map-region(org-promote 1426 1480)
  org-paste-subtree(1)
  org-archive-subtree()

Hopefully, these lines won't get wrapped:

     1	(defun org-get-tags-at (&optional pos)
     2	  "Get a list of all headline tags applicable at POS.
     3	POS defaults to point.  If tags are inherited, the list contains
     4	the targets in the same sequence as the headlines appear, i.e.
     5	the tags of the current headline come last."
     6	  (interactive)
     7	  (let (tags)
     8	    (save-excursion
     9	      (goto-char (or pos (point)))
    10	      (save-match-data
    11		(org-back-to-heading t)
    12		(condition-case nil
    13		    (while t
    14		      (if (looking-at "[^\r\n]+?:\\([a-zA-Z_@0-9:]+\\):[ \t]*\\([\n\r]\\|\\'\\)")
    15			  (setq tags (append (org-split-string 
    16					      (org-match-string-no-properties 1) ":")
    17					     tags)))
    18		      (or org-use-tag-inheritance (error ""))
    19		      (org-up-heading-all 1))
    20		  (error nil))))
    21	    (message "%s" tags)
    22	    tags))

It is clearly stuck in the while loop between lines 13-19 but I'm not
sure why.  Does anyone else experience this behavior?
