Thanks.  It's due to that change:

2013-03-19  Dmitry Antipov  <dmantipov <at> yandex.ru>

	* window.c (Fwindow_combination_limit, Fset_window_combination_limit):
	Signal error if window is not internal.  Adjust docstring.

You could try to work around it by using

            (combination-limit
	     . ,(unless (window-live-p window)
		  (window-combination-limit window)))

in `window-state-get' but I have no idea whether this would break any
things.  In any case it might be simpler to revert the change because
the original behavior was not broken IIUC.
