"destroy" signal handler sample code for Glib bindings

[g4-lisz at tonarchiv.ch]

Hello

Can someone please guide me to some sample code on how to catch a 
"destroy" signal from a DBusGProxy created with new_for_name_owner()?

I'm new to GLib and i have no idea how such signals are caught and 
handled...

I'd like to avoid proxy calls when it had been destroyed:

CRITICAL **: dbus_g_proxy_call: assertion `!DBUS_G_PROXY_DESTROYED 
(proxy)' failed


Any help would be much appreciated!
