Should be fixed, I added a (require 'pp). This is the Elisp pretty
printer library.

Fixed. According to the protocol state machine the quit/interrupt
commands can only be used while Lisp is evaluating something for
Emacs, but they didn't check this before trying to talk to Lisp.

(Probably the real problem is in the state machine - we should be able
to send an interrupt to Lisp at any time. I have another patch to let
Emacs send asynchronous commands to Lisp, so I'll fix this when I
commit that.)
