property changes emited but not captured, why?::

[Yunchuan Geng <yunchuan.geng@nomovok.com>]

Hi,

I am testing map-client python script from bluez-5.30. Everything works 
fine, except that I found I can not capture the properties change signal,
which I confirmed from log did been emitted from parse_subject function 
in obexd/client/map.c

In order to check if the signal is captured in python script or not, I 
have patched the script like this. But have not catch any signal the 
parse_subject
function has emitted.

Could anyone tell me why and how to correctly capture property changes 
emitted by g_dbus_emit_property_changed function.
