Cygwin 1.7 - xfce hangs on shutdown

[Rick]

Hi,

When shutting down xfce 4.6.2 from within cygwin, it prompts me with a 
little window as to whether to save the session, logout, etc.  I unclick 
save the session and then select logout (instead of hibernate, etc).

Once I hit logout, xfce displays the following error in the command 
window and then hangs:

** (xfce4-session:3248): WARNING **: xfsm-shutdown-helper.c:110: Failed 
to connect to the system message bus: Failed to connect to socket 
/var/run/dbus/system_bus_socket: No such file or directory
** Message: xfsm-shutdown-helper.c:274: HAL not available or does not 
permit to shutdown/reboot the computer, trying sudo fallback instead.
