      class Model
  include Mongoid::Document
  include Mongoid::Timestamps
  
  field :foreign_identity
  index :foreign_identity, :unique => true
  validates :foreign_identity, :uniqueness => true
end

      Model.create! :foreign_identity => ''
Model.create! :foreign_identity => '' #uniqueness validation failed
Model.count #reports "2"

Model.where(:foreign_identity => '').first #returns "nil"

      This happens because while creating foreign_identity is given value "", however where method queries for value nil for foreign_identity and so doesn't find any. Same with validation.
      P.S. It seem to only happen if attribute name is foreign_identity.
