crash in xdisp.c: show_mouse_face

[David Reitter]

A user reported a crash under the circumstances described below.
This is the Carbon port of GNU Emacs from March 28, with some patches  
(none to xdisp.c).
Please see the stack trace below, and ask Phil directly in case there  
are questions - I don't have more information.
