wrong python version with :session

wrong python version with :session

[Myles English]

Hello,

When a python source block has a :session header argument, the python
version selected does not appear to respect the value of the variable
org-babel-python-command.

In my .emacs:

(require 'org-install)

(org-babel-do-load-languages
 'org-babel-load-languages
 '((python . t) ))

(setq org-babel-python-command "python2")

In my org file:

#+begin_src python :results output
import sys
print(sys.version)
#+end_src

#+results:
: 2.7.2 (default, Jun 29 2011, 11:10:00) 
: [GCC 4.6.1]

Now exactly the same but with ":session x" header argument:

#+begin_src python :results output :session x
import sys
print(sys.version)
#+end_src

#+results:
: 
: 3.2.1 (default, Jul 11 2011, 12:37:47) 
: [GCC 4.6.1]

So babel has chosen to use Python 3.2 When I wanted to use Python 2.7,
as in the first block, and the value of org-babel-python-command is
still "python2".

Versions:

orgmode commit cae9f947be (Aug 30th)
GNU Emacs 23.3.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.22.1) of 2011-03-10 on bitzer.hoetzel.info

$ ls -l `which python{2,3,}`
/usr/bin/python -> python3
/usr/bin/python2 -> python2.7
/usr/bin/python3

Am I doing something wrong or is this a bug?

Thanks,

Myles

Just ignore this thread, the issue was dealt with in an identical one,
also started by me!
