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 Here is the output of bzr version-info --------------------------------- $ bzr version-info revision-id: rudalics@gmx.at-20110709123238-vs7l1ocolzez5ibf date: 2011-07-09 14:32:38 +0200 build-date: 2011-07-10 12:53:42 -0400 revno: 105058 branch-nick: trunk --------------------------------- These are the sources that I built emacs with.
