If your __unicode__ implementation does not return a unicode object then Python coerces it to unicode. But there are only a limited number of types that Python can coerce to unicode (strings and buffers, or so the message implies). So if you return neither a unicode object, nor a string or buffer, then you get this error. There are places where ugettext_lazy cannot be used. This would appear to be one of them.
