The crash is because xftface_info is NULL, but I can't
reproduce it.  My Emacs configuration is almost the same as
yours.

GNU Emacs 23.0.0.30 (i686-pc-linux-gnu, X toolkit, Xaw3d
scroll bars) of 2007-04-13 on etlken

I run configure with "--enable-font-backend", and start
emacs with "--enable-font-backend".  As you said you are
using Xft font, I think you did the same.  Can't you show me
the exact operation to produce that bug by starting Emacs
with "-Q --enable-font-backend -fn SOMEFONT"?
