Ok, this is still perplexing me, as I have a new version from git and I
still get the error.  The following is complete list (sorry for the long
email!) of what I have done:

* Get a fresh copy of =org-mode= from git and byte-compile:

#+begin_src: sh
  cd ~/install/org-mode
  mkdir new_git_clone
  cd new_git_clone
  git clone git://orgmode.org/org-mode.git
  cd org-mode; make &> make.out
  ln -s ~/install/org-mode/new_git_clone/org-mode ~/install/org-mode/current
#+end_src

During the =make= process, I noticed quite a few warnings.  An example is
below (for a complete copy of =make.out=, see
http://astro.sunysb.edu/cmalone/nolink/make.out

Are such warnings normal?

* Attempt an export of the =org-mode= file found here:
http://astro.sunysb.edu/cmalone/nolink/python_class_lstings.org

Exporting this to PDF, HTML, or ASCII (I didn't try other forms) results in
the following error in the *Messages* buffer: 'Invalid read syntax: "#"'.  I
turned on =debu-on-error= and the *Messages* and *Backtrace* buffers can be
found here:

http://astro.sunysb.edu/cmalone/nolink/backtrace.txt


PS: I had already written most of this before I just saw your email -
hopefully this helps...
