no explanation for disconnect given

On one of my hosts sugar-presence-service more often than not refuses to work with a Jabber server. It connects at first, but disconnects again after a few seconds without any useful explanation:

This ticket is about getting useful information in the logs. Once we got that I can continue debugging the flakeyness (there's nothing useful on the server side either, it just says the client disconnected).
