NameOwnerChanged() is not always called (inconsistent behaviour)

I am using a BusListener and I was hoping to learn the WKN's of all peers by using NameOwnerChanged().

When the client with the BusListener starts up first and then another peer advertises a WKN X, the client is notified of this. (OK!). However, when the other peer starts up first and advertises its WKN, followed by the client with its BusListener, the latter receives NO NameOwnerChanged(). (NOK!) Not really what one might expect, I believe.

The NameOwnerChanged signal is only reliable for locally owned names. If the name is on a remote device the name is not exchanged till a session is established.

For tracking names between buses the FoundAdvertisedName and LostAdvertisedName should be used.
