Bug Description

The dbus sessionbus is not properly terminated on session end (ie logout)
resulting in a stale dbus-daemon-1 processes for each time you login/logout.
Below is ps output after I logged in and out 5 times.
$ ps -x | grep dbus
 7353 ? Ss 0:00 dbus-daemon-1 --fork --print-pid 8 --print-address 6
--session

If anyone is trying to reproduce this, note that (at least on my hoary) this
behaviour doesn't happen if you log out "normally" through the GNOME log out
menu item. It happens if you, for example, do a sudo /etc/init.d/gdm stop.

Using Warty here and it does not seem to matter how seesion is terminated
(normal logout, /etc/init.d/gdm stop, ctrl-alt-backspace) dbus does not get
killed and a new process is created on next login. I found a redhat bug with
some possibly helpful info:

OK, maybe not so fast. dbus-session just doesn't handle signals; I won't fix
this right now, maybe later.
