[O] org-mode fontification error

[Zack Piper]

(Apologies for the second email, didn’t see it go through...)

When attempting to open an Org file (such as my own `config.org'), I
get "org-mode fontification error" appear in the mini-buffer.

I can reproduce it using the following:

Org-mode version 8.2.10 (release_8.2.10 @
/home/zack/ins/share/emacs/25.0.50/lisp/org/) (latest Git master)

GNU Emacs 25.0.50.7 (x86_64-suse-linux-gnu, GTK+ Version 3.16.7) of 2015-12-10
Git: d75849e937af0ecbcdc7bf621aa9bcd43aa75df4

╭────[ r.el ]
│ (require 'org)
│ (setq org-src-fontify-natively t)
│ 
│ (find-file "r.org")
╰────

╭────[ $ ]
│ emacs -Q -l r.el
╰────

╭────[ r.org ]
│ #+BEGIN_SRC emacs-lisp
│ (message "test")
│ #+END_SRC
╰────

All the above produce "org-mode fontification error", and results in
no code blocks being fontified.

Thanks!
