DBus GObject & g_object_unref

[Havoc Pennington]

Not sure I understand what you expect vs. what you are seeing, but 
unref'ing an proxy will not make the remote application exit... if you 
just want to be notified when the proxy is finalized, then use the 
normal gobject features (g_object_set_data, g_object_weak_notify(?))

If you want the remote app to exit, you have to do that in some custom 
way, e.g. by having it include an Exit method. Or for example if you 
want a "single instance" app, you can have each instance exit if it 
loses ownership of a bus name, and allow one instance to take over the 
bus name from an existing instance.
