* The problem
This works:

#+begin_src emacs-lisp 
(message "4") 
#+end_src

#+RESULTS:
: 4

Let's enable some more languages:

#+begin_src emacs-lisp 
(org-babel-do-load-languages
      'org-babel-load-languages
      '((emacs-lisp . nil)
        (R . t)
        (sh . t)))
#+end_src

#+RESULTS:

And try again:

#+begin_src emacs-lisp 
(message "4") 
#+end_src

Debugger message:

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

Your bug report will be posted to the Org-mode mailing list.
