Dear org-mode developer,

I have discovered the following issue with Python code-blocks: Using the
:session header argument leads to errors of the type IndentationError:
expected an indented block if the code block contains indented regions
with empty lines. An example code-block which produces this kind of
error is the following:

#+begin_src python :session
   for k in range(3):

       print(k)
#+end_src

removing the :session header argument leads to correct execution of the
code block. The same is true if the :results output header argument is used.

If the blank line within the for-loop is removed the loop also gets
executed correctly, however after executing the block the error
NameError: name '_' is not defined is raised in the buffer of the Python
session.

The generated info-file is attached to this mail.

Best regards,
Tobias Müller.
