Endliess loop in bp activity plus stream from unknown user

I haven't really decided if this is a bp issue or a bp activity plus plugin issue. Seeing as how the comment was posted via the plugin's text box, I thought I'd post here as well as the bp forum.

I just had someone post a comment to the ACTIVITY STREAM. They had no username or avatar that I could see. When I clicked the VIEW link it resulted in an endless redirect loop. Bug or intentional hack?

This is the DB entry. Note that the user_id is “0?. Yet when I check wp_users the lowest user id that I see is my ID… the admin, which is “1?. http://i.imgur.com/iUZGq.png

This is what appears in the URL bar at the top of the browser… I stopped it, but eventually it crashes and I get a redirect loop message – http://i.imgur.com/7LWYF.png

Anyone have any idea what the problem is? I ended up logging in as admin and just clicked the DELETE link next to the comment in the activity stream
