Well that's just freaky.
Today it does not work with gamba but only as gambas :-\  wtf !

Does it help you with your own problem defining your handler m8?

what's important is the prefix for the handler, in my case,
org_gambas_dbsend_MyEvent() matches the interface name org.gambas.dbsend
but with underscores not dots.
Also using DBus.Raise() to trigger it.

And on the other side you have to use the _Signal(Name As String, Arg as
Variant[]) event of the DBusSignal watcher.
