Hi, everyone -

First post to the list. Guess I should start out by saying, Carsten et al, you
guys rock! Thanks for org-mode!

* Problem: I can no longer insert new outline headings via the usual M-RET
  binding.

Here's an overview of my setup:

** os: debian (wheezy/sid amd64)
** emacs: gnu emacs (23.4.1 - plain-vanilla distro)
** window manager: xmonad 0.10
** terminal: xfce4-terminal + tmux 1.6
** org-mode: development (via git) 

* What have I tested?

** running emacs under a different terminal (urxvt and xterm)
** running outside tmux in a normal session
** disabling all my ~/.emacs.d/ modifications apart from setting my load-path
   and the bare minimal [0] to instantiate org-mode
** running org-7.8.09 (stable) and org-7.8.06 (distro)

None of that fixed it.

* C-h C-b indicates the binding is in place.

* output of xev / xmodmap looks normal

M-x org-insert-heading works just fine. At this point I think I've tried
looking at all the complicated things. Past experience leads me to believe
there's something completely stupid and obvious that I'm not thinking of,
which is why I'm turning to you lot. Please, someone make me feel stupid and
save my sanity!!! ;-)
