At least that's nice in itself...  (I now keep common config data in a git
submodule that I clone and load at export time with Make).

It would seem so.  Unless if you perhaps did not load your org-git version
in the "emacs -q" setup.  But at least on my system the recent Org is
loaded with "-q" (I keep org in the system-wide site-lisp).

This should be completely orthogonal.

Hmm, I'm thinking out loud here, but perhaps you could try deploy
something like the following to detect *where* org-display-inline-images
is called.

#+BEGIN_SRC emacs-lisp
  (defun a-pix-is-worth-a-1000-words (&optional &rest args)
    (with-temp-file "/tmp/backtrace.txt"
      (goto-char (point-max))
      (insert (format-time-string "++++ %s ++++\n"))
      (let ((standard-output (current-buffer))) (backtrace))))

  (add-function :before (symbol-function 'org-display-inline-images)


m-mm-mmm-mmmm bacon!
