Hi Ista,

Org-mode version is 7.9.3e (7.9.3e-3-gb07a9b

i.e. loading current trunk.

When following your prescription, bug does not occur.

My from way to load languages was

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

If I load this first, then your print-example shows error like indicated in subject line.

Something wrong with this code?

Thanks all,

Andreas
