I did figure this out a couple of hours after I discovered the weird behavior.

I can save you some trouble - bracketed paste support works fine, the terminal 
sends the right control codes :-).

The problem is that I had this key-binding in some emacs-lisp code I wrote a 
while ago:

(global-set-key [(meta \])] 'something)
(global-set-key [(meta \[)] 'something-else)

After removing those global key bindings, it works great.

It might be worth putting some nicer error-reporting around those though, since 
M-] and M-[ are perfectly cromulent keys to want to bind (and I still bind 
them, I just have an (if (not (eq window-system nil))) around it now.

Thanks,
