Click on the link with many "likes" under a post and the javascript popup only displays a name and a picture for the first one who is not on your friends list and potentially another one who is your friend. I can't believe nobody has noticed this in the 9 months!

I am currently using the following modules:
Facebook Stream 6.x-2.0-beta1
Fbconnect 6.x-1.x-dev
jQuery UI 6.x-1.3
jQuery Update 6.x-2.x-dev

However, I experienced the same problem with all other versions of Facebook Stream and Fbconnect that I tried.
