multi-web-mode conflict: "Making autopair-emulation-alist buffer-local while locally let-bound!"

[fecundf]

I'm seeing this warning, when in multi-web-mode and backspacing/re-typing a closing paren:

Making autopair-emulation-alist buffer-local while locally let-bound!

You do have to install multi-web-mode to see this, alas, but the error does seem to point to auto-pair. Here's how I reproduce it:

Set up multi-web-mode, this is in my .emacs:

(require 'multi-web-mode)
(setq mweb-default-major-mode 'html-mode)
(setq mweb-tags '((php-mode "<\\?php\\|<\\? \\|<\\?=" "\\?>")
                  (js-mode "<script[^>]*>" "</script>")
                  (css-mode "<style[^>]*>" "</style>")))
(setq mweb-filename-extensions '("php" "htm" "html" "ctp" "phtml" "php4" "php5"))
(multi-web-global-mode 1)

Open an empty buffer and type:
<?php foo()

The M-x autopair-mode, multi-web-mode
Turn off any other minor modes that may have come up
Delete the final closing paren, and retype it

I now see:

Making autopair-emulation-alist buffer-local while locally let-bound! [2 times]
call-interactively: Wrong type argument: listp, set-from-style

multi-web-mode appears to do a lot of variable-changing tricks to support multiple major moes in a single buffer. I would suggest you also report the bug there, as I have no idea as to how to fix this at the moment.
