rails session_store odd behaviour

Question

Hi,

I am using active_record_store in a rails application which is storing this in session session[:email] = "[email protected]"

now this works fine in the action. but when this action gets over and is redirected to another page, which also accesses the same session[:email] I get an error

undefined method `eq' for nil:NilClass

this should probably mean that i am trying to compare values at some place i am not allowed to. but i cannot see anything like that in the code.
