Hi.

Let me add a few bits of diagnostic here.

I've tried with the following setup to try and isolate the problem :

* stating X with startx so that the "failsafe" X session is started, with 
  x-session-terminal alternative set to xterm
* disabling use-session-dbus in /etc/X11/Xsession.options
-> when in xterm, no session dbus launched as checked with 'ps -edf f' 
(by the way, I like this nice pstree like option)

* then starting gnome-session --failsafe
-> 2 dbus-daemon :
olivier  17429     1  0 00:33 ?        Ss     0:00 /usr/bin/dbus-daemon --fork --print-pid 5 --print-address 7 --session
olivier  17430     1  0 00:33 pts/0    S      0:00 dbus-launch --autolaunch efd0e38138c517c9110cd38748dfa7a4 --binary-syntax --close-stderr
olivier  17438     1  0 00:33 ?        Ss     0:00 dbus-daemon --fork --print-address 18 --print-pid 20 --session

-> problems in gnome-session's output :

SESSION_MANAGER=local/asustour:@/tmp/.ICE-unix/17424,unix/asustour:/tmp/.ICE-unix/17424

So I confirm that gnome-session and/or it's children are starting 
2 dbus-daemons, when there was no dbus manually launched before.

I hope this helps.

Next step would be to trace what's happening in the gnome-session, I guess... 
Any help in doing so much welcome.

Best regards,
