bug#15686: 24.3.50; Face related crash in current trunk

Subject: bug#15686: 24.3.50; Face related crash in current trunk
Date: Tue, 22 Oct 2013 20:20:19 +0200

With emacs -Q I evaluated the following form:


(custom-set-faces
 ;; custom-set-faces was added by Custom.
 ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.

Then I typed C-h a and moved my mouse around the window.  The backtrace
I eventually obtained is:
