Hi Julien,

I don't have any clever ideas about this, so I'm just going to suggest
the obvious: first a sanity check that it doesn't occur with emacs
-Q. Then some sort of quasi-binary search through your emacs
customisations. It looks like you're storing your emacs customisation in
an Org file, so you can knock out entire trees with :tangle: no
properties.

Dan

p.s. On a completely unrelated note, if you haven't already tried it:

(add-hook 'emacs-lisp-mode-hook 'pretty-lambdas)

where the `pretty-lambdas' function is in starter-kit-defuns.org at
git://github.com/eschulte/emacs-starter-kit.git

(defun pretty-lambdas ()
  (font-lock-add-keywords
   nil `(("(?\\(lambda\\>\\)"
          (0 (progn (compose-region (match-beginning 1) (match-end 1)
                                    ,(make-char 'greek-iso8859-7 107))
                    nil))))))
