Hello, When I use a python code block in a document any export-as-html results in the error "Invalid file-name". Without a code block the export goes without a hitch. Other exports work no probs such as export-as-ascii. The code block within the document acts as expected, it is only the export that fails. I was on org7.5 but updated to 7.8.03 but have the same result. Also, it is only the python code blocks that fail, others work. My babel setup is (org-babel-do-load-languages 'org-babel-load-languages '( (dot . t) (sh . t) (python . t) (emacs-lisp . t) )) (setq org-babel-python-command "python2.6") My code block is #+begin_src python :results output print "hi" #+end_src #+results: : hi Does anyone have any tips on what I might do to troubleshoot this. Could it be something else in my setup or system? Any else ever experienced this? cheers, aaron.
