Re: [BUG][Babel] Exporting text before heading

Hi Nicolas,

I was able to export your example to html without any problems, however
I did receive the same error you mentioned when exporting to LaTeX.

The attached patch fixes the LaTeX export on my system, please give it a
try and let me know if it works for you.  I'm going to look into this a
little bit more, as it seems that for LaTeX export the "#+begin_src org"
block is being processed /twice/ by org-exp (probably due to the LaTeX
exports mechanism for first exporting the header of a file and then
exporting the body), which is not desirable and could be the root issue
which this patch may just paper over.

Cheers -- Eric
