Comment 4 for bug 1031391

Hi Robert. Apologies for the delay in responding. Summer vacations and all. I did end up fixing this in a more general way, by ensuring that all values are pickled if they are not str or unicode. I think it's a programming error if the key is ever non-str/unicode so that raises an exception. I also mangle the key name when using a pickle so that unpending the data can restore the original object.

Thanks very much for the contribution to Mailman!
