Hi list,

I'm using Org-mode version 8.2.10 (8.2.10-dist @
/Users/fullofcaffeine/.emacs.d/vendor/org-mode/lisp/) -- which as you can
see was installed in a custom location, with emacs GNU Emacs 24.3.1
(x86_64-apple-darwin11.4.2, Carbon Version 1.6.0 AppKit 1138.51) of
2014-04-03 on Yukikaze.local.

After updating to org 8.2.10, I started getting some cryptic (for me)
errors with org-babel. My main conf file is an org file which gets
processed by babel to .el. It used to work fine, but now I get this
(stacktrace follows):

`

Here's my init.el file: http://pastie.org/private/1eajm9mkmqfjbpr0z3ska

Does anyone know what is the issue?

Thanks,
