... my entry for the dirtiest piece of code possible (but it works for
now):

(defun vb-massage-includegraphics (str backend opts)
  (replace-regexp-in-string ".png}" ".pdf}" str))
(add-hook 'org-export-filter-final-output-functions
          'vb-massage-includegraphics)

Am I on the right track? Meaning, after adding a test on the backend,
possibly a file existence check and so on. Or am I missing a simpler
way?

Cheers,
