Yes there are two issues, so I will reassign one of them.

First issue, disabling "use-session-bus" breaks GNOME. There is no
reason to not run dbus-launch when logging in a GNOME session, so I
strongly recommend to apply the patch I already suggested to dbus-x11.

Second issue, there are cases when none of the scripts
in /etc/X11/Xsession.d are read. This implies the following conditions:
      * using startx instead of a display manager
      * having a .xinitrc file

I consider you really should know what you are doing in this case. If
you are launching gnome-session by hand in your .xinitrc, you should do
what it takes to start it, and it is not "gnome-session" but now
"dbus-launch --exit-with-session gnome-session". If you don’t know what
you are doing, don’t use a .xinitrc.

I guess that several of you are using .xinitrc for bad reasons, namely
starting other stuff before gnome-session. This can be achieved in a
much better way by using .xsessionrc or .gnomerc (both are sourced
before executing gnome-session).

Nevertheless, there is a bug in gnome-session: autospawning the D-Bus
daemon, which is done by the GConf library, leads to race conditions.
Spawning the daemon if it is not here yet should be the first thing
gnome-session does. A simpler way might be to throw an error dialog if
there is no D-Bus daemon, and frankly I’m tempted to do that given the
amount of bugs you’ll encounter if dbus-daemon is not started before
gnome-session.

Cheers,
