Hi Nicolas,

The problem is that the byte code comes from Python mode.
I solved the problem with this:

$ diff -uw contrib/lisp/org-eldoc.el contrib/lisp/org-eldoc.el
--- contrib/lisp/org-eldoc.el   2016-02-29 11:13:22.330099500 +0100
+++ contrib/lisp/org-eldoc.el   2016-07-04 07:11:10.466144400 +0200
@@ -155,7 +155,8 @@
              (string= lang "golang")) (when (require 'go-eldoc nil t)

 (go-eldoc--documentation-function)))
            (t (let ((doc-fun
(org-eldoc-get-mode-local-documentation-function lang)))
-                (when (fboundp doc-fun) (funcall doc-fun))))))))
+                (when (or (and (symbolp doc-fun) (fboundp doc-fun))
+                         (functionp doc-fun)) (funcall doc-fun))))))))

 ;;;###autoload
 (defun org-eldoc-load ()



In python.el, one can find this around line 5129:

  (if (null eldoc-documentation-function)
      ;; Emacs<25
      (set (make-local-variable 'eldoc-documentation-function)
           #'python-eldoc-function)
    (add-function :before-until (local 'eldoc-documentation-function)
                  #'python-eldoc-function))

which stores byte code in eldoc-documentation-function, which makes
fboundp fail because the object is not a symbol. However it is a function.
