Facebooker talk - Dec 2007 - upgraded to rails 2.0.1 and borked sessions

I just pushed my facebook app up to 2.0.1 and noticed that I am now  
getting these errors:

ActionView::TemplateError (Session key invalid or no longer valid) on  
line #3 of users/index.fbml.erb:

It appears that I get the facebook_session object back but when i  
introspect and try and get the user''s name or something i get the  
session error. Has anyone else had these problems?

This is a follow up message to my last post. The error was with 2.0.2  
not 2.0.1

Here is what I know about the problem. I created a new app in 2.0.2   
e.g. : "rails some_app"
when i did a simple introspection of the user object (for example  
getting the user''s name) i''d get the invalid session.

However, creating an app using the rails 2.0.1 gem e.g.: "rails  
some_app"
did not produce the error on the same introspection. Now, I did try  
changing the RAILS_GEM_VERSION = ''2.0.1'' in the version the
2.0.2 app
created but it still would not work for me (even though it should  
have been using the 2.0.1 gem).

This really seems like black magic to me, and I wish i had more info  
to help anyone else who might find themselves in a similar situation.  
However, I would be interested to know if someone has been able to  
generate a rails app from the 2.0.2 source and get facebooker to run  
without getting the invalid or expired Session Key.
