One thing I noticed on a couple of my boxes, with certain versions of
dbus (don't remember which), the session daemon would quit immediately
if dbus-launch was passed the --exit-with-session parameter.  After
starting a fresh Xfce session, check to make sure you have an instance
of 'dbus-daemon' running as your username.  On most systems, you will
have TWO instances of this: one running as another user (the system
bus), and one running as your user (the session bus).

Actually, when you updated dbus, did you restart Xfce?  Depending on
which version your old version of dbus was, it's possible you had an old
daemon running with new (incompatible) libraries trying to talk to it.
