Thanks for your answer!  I tested with your file.  I only get the
'Malformed mode-line'.  (The questions about unsave variables was my
mistake.)

But the session 'foo' is still not started, but the code blocks are
evaluated as if there was no session specified:

#+begin_org
# -*- org-babel-default-header-args:R: ((:session . "foo")) -*-
#+Title: Example
#+Author: Eric Schulte

For more information on file local variables see [[info:elisp#File%20Local%20Variables][info:elisp#File Local
Variables]].

Because there is a default :session values assigned locally for R
blocks we have the following.

#+begin_src R
  x <- 1
  x
#+end_src

#+RESULTS:
: 1

#+begin_src R
  x
#+end_src

#+RESULTS:

But non-R code blocks do not have a default session value.

#+begin_src sh
  date
#+end_src

#+RESULTS:
: Mi 27. Mär 21:18:49 CET 2013
#+end_org


Is that just not working for me?  And any ideas, what I could do about
it?

Regards,
Andreas
