Rails Ruby on Rails

I'm shifting my Rails 2 code to Rails 3. I've an active record query

Group.find(:all, :select => 'groups.name',:include => :owner)

In model groups.rb, i've an association defined:
belongs_to :owner, :class_name => "Member", :foreign_key =>"owner_id"

I'm getting an error while running above query:

ActiveModel::MissingAttributeError: missing attribute: owner_id

I'm using Rails 3.0.6. Seems like there's a bug introduced in the ActiveRecord 3.0.6. Kindly look into this issue and fix.

Thanks,
