interaction between python-mode.el and org-mode.el causes traceback.

[Greg Novak]

If I load a python source file using python-mode.el, and then subsequently look at a .org file using org-mode.el, I get an error:

Lisp error: (wrong-type-argument stringp nil)

and then I cannot see my .org file (nothing is displayed in the buffer).

Specifically the steps to reproduce are:

1) run 'emacs --no-site-file --no-init-file'
2) eval "(require 'python-mode)" to load python-mode.el
3) find-file "some/python/file.py"
4) find-file "some/org/file.org"

and I get the above error. If any of the above steps are omitted (ie, if I load python-mode.el, but don't actually look at a python file), I don't get the error. I've included a traceback below. I'm also submitting this to as a bug to org-mode.

I'm running:
OS X 10.7.5
Emacs 24.2.1
org-mode 7.8.11
python-mode 6.1.0

Backtrace follows:

Can't reproduce. Might be fixed already.
Please check out current trunk from bazaar

bzr branch lp:python-mode

Indeed, seems to work now. Apologies for the spurious report.
