Today's :ignore-defface changes: Emacs segfaults immediately

[Romain Francoise <romain@orebokech.com>]

After this change:

2005-11-20  Chong Yidong  <cyd@stupidchicken.com>

	* xfaces.c (Finternal_set_lisp_face_attribute): Use
	:ignore-defface for new frame defaults when `unspecified' is
	supplied.
	(Finternal_get_lisp_face_attribute): Hide :ignore-defface.

Emacs segfaults immediately after startup.  It seems to be working fine
with `emacs -q', but not with my config file.  Reverting this change
makes things work again.
