Hi Nicholas,

I'm happy that you're enjoying Org-mode.

I'm having trouble reproducing this problem.  As far as I can tell
`org-babel-tangle-lang-exts' is only called from language specific files
which should be required after that variable has been defined.

Is it possible that your configuration is loading language-specific
files or touching org-babel-load-languages before you are calling
(require 'org-install)?

Is the `org-export-htmlize' set to a non-nil value on your system?  If
so then that could be the cause of the problem.  If it is set to a
truthy value, and htmlize-region is defined in your Emacs, then I'm not
sure what the problem could be.
