Django 1.6 in GAE, iexact error, even with dbindexer

[GAEfan]

I tried to update to Django 1.6 from 1.5.5. Mostly works, except when I try to do a search in User admin. The default searches for email iexact. Django gives me the 'Lookup type 'iexact' isn't supported.' error.

I am using djangoappengine and dbindexer. Dbindexer does load the __iexact field into the db. The

register_index(User, {
'username': 'iexact',
'email': 'iexact',
})

does seems to register. But, this version of Django 1.6.11 does not like the iexact.
