This is a perfectly good bug report :) and it's a case that should definitely be considered.  Probably we should up-convert from bytes automatically in the places where we know python will be using the values as identifiers, including callRemote and the keys in a __dict__.

This is unfortunately very tricky to know though, if we support serializing both bytes and strings :-\.
