Is there something wrong with the default dbus policy?

[Bear]

hi,
I just found a problem of dbus. I installed xorg and gnome2-lite via pkg_add -r with PACKAGESITE = 8-stable. Then I added dbus_enable="YES" and hald_enable="YES" into /etc/rc.conf and mounted /proc. I also sure that my localhost and my host name with domain name is pingable.
My ~/.xinitrc is list below:
exec ck-launch-session gnome-session

When I use a normal user to launch startx, the gnome-panel and some other process would show a error:
** (gnome-panel:69812): WARNING **: Could not ask session manager if shut down is available: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

And also, the gnome-panel took a long time to appear since the desktop shown.

But when I login as root and launch startx, this error message disappered and everything worked well.

Could you help me to solve this problem? thx
