Hi, I have a problem with Python src blocks indentation. At the moment, I export IPython notebooks with ox-ipynb (https://github.com/jkitchin/scimax/blob/master/ox-ipynb.el from scimax by John Kitchin) All the lines but the first one in src code blocks have 2 superfluous leading spaces. If I set (setq org-edit-src-content-indentation 0) then the code blocks are ok. Any idea where to look for to track this problem further down ? Best regards, Fabrice
