[O] Bug: conflict with python-mode [7.8.11]

[Till Junge]

This may be a python-mode bug but I'm new to all of this.

I observe the bug only when using org-mode together with python-mode. My
org-mode setup is supposed to load org-cdlatex-mode:

(autoload 'org-cdlatex-mode "cdlatex" "Enter org-cdlatex mode" t)
(add-hook 'org-mode-hook 'turn-on-org-cdlatex)

and this works fine when python-mode is not loaded. When I load python
mode, however (trunk version)

  (setq py-install-directory "~/.emacs.d/python-mode.el-6.1.0")
  (add-to-list 'load-path py-install-directory)
  (require 'python-mode)

Then cdlatex mode is not loaded anymore and it's impossible to unfold
any headlines. Org-mode becomes entirely useless:

#+TODO: TODO CODE(c) DOCU(d) PLAN(p) PROJ(j) QUESTION(q) TEST(t) |
DONE(d) ANSWERED(a)
#+TAGS: PHONE(p) URGENT(u) MAIL(m)  CODE(c)
#+STARTUP: inlineimage
#+AUTHOR: anauthor
#+TITLE: a title
...

when I try to expand the '...' (which btw looks lice '* Introduction...'
when everything works fine), I get the message "outline-end-of-heading:
Wrong type argument: stringp, nil"

What to I do?
