Hi Michael,

The blocking you observed when dbus.el is loaded doesn't occur with a 
build from the Emacs trunk (r101187).  But I don't know how to test the 
dbus functionality after loading dbus.el.  If we find it works there, 
maybe the problem is just a matter of backporting some patch to Emacs 
23.2.  Can you tell me how to test dbus in emacs?  Or do you want me to 
send you the executable and let you test it?

Ken
