References with unicode attributes don't work as expected

Gabriel Rossetti reported in the list:

"""
I found the error if anyone ever has this too : in my reference
declarations, I used a unicode string... The error isn't very indicative
of the problem, but if you replace :

language = Reference(languageId, u"Language.id")

with :

language = Reference(languageId, "Language.id")

it works.
