root mail and dbus error

I use FreeBSD 7 with Gnome , today I go to this directory
and open root mail . I see this message many many ,

Dec  7 16:51:19 Mostafa gnome-keyring-daemon[1255]: error connecting to D-BUS system bus: Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory

How I fix this error ??
Start dbus?

Looks like it should be started automatically if you enable Gnome via setting [font="Courier New"]gnome_enable[/font] in rc.conf; this will start other things too. Otherwise, you can set dbus_enable on its own in rc.conf. To do it once, the easiest way is "[font="Courier New"]/usr/local/etc/rc.d/dbus forcestart[/font]".
