"Autoloading failed to define function org-babel-do-load-languages"

[Karl Voit <devnull@Karl-Voit.at>]

Hi!

I'm in the process of switching from ~/.emacs.d/init.el to
~/.emacs.d/config.org using the method described on [1].

Org-mode from maint Git repository overruled via following lines
right at the top of my ~/.emacs.d/init.el:
| (add-to-list 'load-path "~/.emacs.d/contrib/org-mode/lisp")
| (add-to-list 'load-path "~/.emacs.d/contrib/org-mode/contrib/lisp" t)

All I did was moving the working elisp configuration into multiple
emacs-lisp blocks. So the content of config.org/config.el should be
OK.

When I start emacs, I got following error:

| Debugger entered--Lisp error: (error "Autoloading failed to define function org-babel-do-load-languages")
|   (org-babel-do-load-languages (quote org-babel-load-languages) (quote ((python . t) (shell . t) (org . t) (emacs-lisp . t) (sql . t) (restclient . t))))

|   load-file("~/.emacs.d/config.el")
|   (let ((orgfile (concat my-user-emacs-directory "config.org")) (elfile (concat my-user-emacs-directory "config.el")) (gc-cons-threshold most-positive-fixnum)) (if (or (not (file-exists-p elfile)) (file-newer-than-file-p orgfile elfile)) (progn (my-tangle-config-org) (save-buffers-kill-emacs))) (load-file elfile))
|   eval-buffer(#<buffer  *load*> nil "c:/Users/karl.voit/AppData/Roaming/.emacs.d/init.el" nil t)  ; Reading at buffer position 3295
|   load-with-code-conversion("c:/Users/karl.voit/AppData/Roaming/.emacs.d/init.el" "c:/Users/karl.voit/AppData/Roaming/.emacs.d/init.el" t t)
|   load("c:/Users/karl.voit/AppData/Roaming/.emacs.d/init" t t)
|   #[0 \205\262

I get it with Debian GNU/Linux stable with latest emacs-snapshot,
Xubuntu 16.04 with its emacs, and with Emacs 24.5 on Windows. The
latter produced the message above, obviously.

The code that causes the error seems to be:

| (org-babel-do-load-languages
|    'org-babel-load-languages
|    '(
|      (python . t)
|      (shell . t)
|      (org . t)
|      (emacs-lisp . t)
|      (sql . t)
|      (restclient . t)
|      ))

A rough guess is that Emacs is using the built-in Org-mode to load
the config.el. I can not confirm this because "M-x org-version"
results in "command-execute: Autoloading failed to define function
org-version".

Do you have any tip for me?
