    work around for obscure problem occuring with some obsoletes
    occasionally rpm sends along an extra callback event that wasn't in the
    transaction set to begin with. This ensures that if we receive those we
    don't explode. Thanks to Fajar A. Nugraha for providing with the
    replicating case and a system to test it on.
