This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgement at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

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
