Hi,

I'm running the following system:

Emacs  : GNU Emacs 23.2.1 (i686-pc-linux-gnu, GTK+ Version 2.24.4)
 of 2011-04-04 on rothera, modified by Debian
Package: Org-mode version 7.7

I've run into a problem with #+begin_src #+end_src blocks:
Whenever I trying to have a one-element python list inside of such a block the 
pdf-export will fail with 

(wrong-type-argument stringp nil)

Here comes a minimal example:

------------------------------------
* Some section

This works fine:

#+begin_src python
    print [0,1,2]
#+end_src

This does not work:

#+begin_src python
    print [1]
#+end_src
------------------------------------

(For some reason I needed to include the src-block in some section. 
That is probably an unrelated problem.)

The trace of this example is

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  string-match("ORG-LIST-END-MARKER\\'" nil)
  org-export-latex-preprocess((:emph-multiline t :for-backend latex :comments

I don't want to exclude the possibility that this has to do with my particular 
setup.
If you cannot reproduce this problem, I'll have a look whether there's anything 
relevant in my config files.

Daniel
