gnome-screensaver crashed in the -CURRENT box

Hi all,

I am running FreeBSD 7.0-CURRENT, which is updated at Feb 22. I
installed gnome by packages. When I run gnome-screensaver, it crashed,
the output is:

----------------------------------
zeuux_at_zeuux:/usr/home/zeuux$ gnome-screensaver
GTK Accessibility Module initialized

** (gnome-screensaver:1587): WARNING **: AT_SPI_REGISTRY was not started
at session startup.

** (gnome-screensaver:1587): WARNING **: IOR not set.

** (gnome-screensaver:1587): WARNING **: Could not locate registry
process 1587: arguments to dbus_connection_add_filter() were incorrect,
assertion "connection != NULL" failed in file dbus-connection.c line
4954.
This is normally a bug in some application using the D-Bus library.
  D-Bus not compiled with backtrace support so unable to print a
backtrace
Abort trap: 6 (core dumped)
--------------------------------------

The dbus packages I used is:
------------------------------------
pkg_info|grep dbus
dbus-1.0.2          A message bus system for inter-application
communication
dbus-glib-0.72      GLib bindings for the D-BUS messaging system
-------------------------------------

Anyone has idea? I need gnome-screensaver to lock computer when I left.
Thanks.
