bug: wrong-type-argument when trying export to pdf.

I am having a problem and getting a wrong-type-argument error when trying to run `org-beamer-export-to-pdf' on the attached file `debug.org' (see backtrace below). The problem also occurs when running `org-latex-export-to-pdf'. 

The bug can be reproduced using `emacs -Q' with the configuration provided in `simple-config.el'.

Note that the problem can be solved by commenting out the lines:
    (org-babel-do-load-languages
     'org-babel-load-languages
     '((R . t)
       (emacs-lisp . t)
       (latex . t)))

yet doing this then makes it not possible to run C-c C-c on the R src block (without those lines you get an error about not being able to find ESS).

Am I just setting up org-babel incorrectly or is this a bug?

Best,
Justin
