emacs-unicode-2 crashed when starting

[Felix Wong]

Hi,

I compiled the latest cvs version of emacs-unicode-2 branch, and when
I tried to start it, it crashed with SIGSEGV. I configured it with:

./configure --with-xft --with-freetype --enable-font-backend
--prefix=/opt/emacs23 --with-x-toolkit=gtk

and the backtrace is:

Is there any workaround to deal with this problem?

Thanks in advance.
