PresenceNotificationReceived RemotePresentityNotification.PersonalNote.Message is empty string when note is changed

Question

Right now I have a RemotePresenceView for which I subscribe to the PresenceNotificationReceived event. The event is correctly getting fired when I change the presence or note in the Lync Client but when it handles the event the RemotePresentityNotification.PersonalNote.Message is an empty string. The RemotePresentityNotification.AggregatedPresenceState is correct but the personal note never is. What's the deal?

I also have the question posted on the microsoft forums: http://social.msdn.microsoft.com/Forums/en-US/ucmanagedsdk/thread/70f249a8-9f55-4e85-b4e4-bd5d18727b9f/;
