Hi Simon,

thank you :)

Yes, it's also documented.

Oh, you are right! Somehow, I was totally
mixed up! But I guess, I figured out what disturbed me:  
For sure it is a bad idea to use the
object, if the timing is like this:

1. g_object_unref(conn);
2. g_dbus_connection_emit_signal(conn);
=> Object is already freed. User deserves the crash ;)

But what is, if the timing is like this:

1. g_dbus_connection_emit_signal(conn);
2. g_object_unref(conn);

I haven't seen that the "g_dbus_connection_emit_signal"obtains
a reference to the connection! 
Shouldn't it do so, to be sure that
the connection is not freed "during" the call?

Best regards
