Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':




I've discovered a problem with org-mode on the trunk version of emacs;
typing ctrl-c ctrl-c to add a tag results in "Wrong type argument:
listp, t".

Here are steps to reproduce:

(1) Place the following in a file named "foo.org" (not including the
lines of "=" signs.)

==================================================================
# -*- mode: org; -*-

#+STARTUP: logdone
#+TAGS: bb(b) dw(d) holiday(a) meeting(m) note(n) q(q) releng(r) sysadmin(s) 
eng(e) other(o)

* Top level
** second level 1
*** third level 1                                                         :b:
    CLOCK: [2011-07-10 Sun 12:44]--[2011-07-10 Sun 12:44] =>  0:00

** second level 2
*** third level 2                                                         :b:
    CLOCK: [2011-07-10 Sun 12:46]

material for third level
==================================================================

(2) Open foo.org with emacs:

    emacs -Q foo.org

(3) place point in the first column of "third level 2" (line 12).

(3) Attempt to add the "meeting" tag to line 12 by typing "C-c C-c m
RET".

Expected behavior: after typing C-c C-c, org mode should present a
list of pre-defined tags.  Emacs 23.3 exhibits this behavior.

Observed behavior: typing C-c C-c produces the following message in the
minibuffer: Wrong type argument: listp, t
