[Facebooker-talk] Session Expired for Profile Publishing

[Mike Mangino]

The session expired messages normally mean that the user whose session  
you are using has uninstalled the application. Are you sure the  
session is valid?

Try calling session.user.name to make sure you can make API calls with  
that session.
