I installed some fixes.  With the new code, the emacs
configured with '--with-x-toolkit=lucid
--enable-font-backend' works.

But, if I configured emacs to use Gtk, emacsclient causes
segfault as this:

(gdb) bt
#0  0xb78cf727 in XFreeGC () from /usr/X11R6/lib/libX11.so.6
#1  0xb7c728be in ?? () from /usr/lib/libgdk-x11-2.0.so.0
#2  0x00000000 in ?? ()

Lisp Backtrace:
"delete-frame" (0xbfdb6ae4)
"call-interactively" (0xbfdb6d44)

and it's reproducable with the emacs before unicode merge.
On this system, the version of Gtk+ is 2.6.4.
