For posterity, the answer here is to call GetConnectionUnixUser on the
bus, rather than using the connection method (which is designed for
point-to-point rather than messages sent over the bus).

<walters> python -c "import dbus;
bus=dbus.SystemBus().get_object('org.freedesktop.DBus',
'/org/freedesktop/DBus'); print dbus.Interface(bus,
'org.freedesktop.DBus').GetConnectionUnixUser(':1.11')"
<walters> where ':1.11' is the return value from dbus_message_get_sender
