[Orgmode] Error about TODO sequence states with 6.09 on Emacs 22.1.1

[Daniel Clemente]

  Hi, I'm seeing a problem with TODO states in the latest org-mode version.


.emacs file to reproduce the bug::

---------
(add-to-list 'load-path "~/.emacs.d/org-6.09")
(require 'org)

 (add-to-list 'auto-mode-alist '("\\.org$" . org-mode))
 (define-key global-map "\C-ca" 'org-agenda)

(setq org-agenda-files (quote ("/tmp/test.org")))

(setq debug-on-error t)

(setq org-todo-keywords
      '( (sequence "START(s)" "|" "ENDED(e)")
         (sequence "TODO(t)" "|" "DONE(d)")) )
---------


The file /tmp/test.org must exist, but its content doesn't matter; it can be 
empty.


Sequence to reproduce the bug:

1. open emacs
2. C-c a a
3. You get this error:

Debugger entered--Lisp error: (wrong-type-argument stringp (sequence "START(s)" 
"|" "ENDED(e)"))
  regexp-quote((sequence "START(s)" "|" "ENDED(e)"))

"TODO(t)" "|" "DONE(d)")) "\\|")
