emacs-unicode-2 crashed in zh_CN.UTF-8 environment

[Felix Huang]

Hi, all.

I compiled the latest CVS version of emacs-unicode-2 branch in Ubuntu
Edgy, and run it in a zh_CN.UTF-8 environment. Emacs crashed at the
splash screen. If I turned off the splash (setq inhibit-splash-screen
t), it was normal until I manually invoked the splash. And in some
files, like a TeX file in LaTeX mode (with auctex), all characters in
section names were squares.

When I changed the environment variables (LC_ALL, LANG) to
en_US.UTF-8, emacs did not crash at either splash screen or other
pages that were crashed at. However, most characters were represented
as squares thus it was incapable of editing.

I configured the emacs with:
  ./configure --with-xft --with-freetype --enable-font-backend
  --prefix=/opt/emacs23 --with-x-toolkit=gtk

My window manager is xfwm4-4.3.99.2 (rev 23334). And it is a XFCE
desktop.

The backtrace of the problem is listed below:
