[O] :RESULTS: drawer exported in LaTeX

[Roland DONAT]

Dear Orgmode community,

I have this piece of python code that generate Orgmode text :

#+NAME: test
#+HEADER: :session test1
#+HEADER: :results value drawer
#+BEGIN_SRC python   
a = "** H1\nblabla\n** H2\nbloblo"
a
#+END_SRC

#+RESULTS: test
:RESULTS:
** H1
blabla
** H2
bloblo
:END:

But when I export my document in LaTeX, the :RESULTS: drawer appears in the 
final pdf which it's not cool...

I have a d:nil in my OPTIONS header.

My configuration :
- Org 8.2.5h on Linux Mint 16. 
- Python 3

Any help would be much appreciated! Thanks.

Roland.
