Recursion issue with ListField of ReferenceField

[prologic]

I'm trying to use ListField of ReferenceField
to maintain a list of user channels of my User model
as well as a list of users in my Channel model.

Model:

# Module:   models
# Date:     16th August 2014
# Author:   James Mills, prologic at shortcircuit dot net dot au


"""Data Models"""


from circuits.protocols.irc import joinprefix

from redisco.models import Model
from redisco.models import (
    Attribute, BooleanField, DateTimeField,
    IntegerField, ListField, ReferenceField
)


class User(Model):

    host = Attribute(default="")
    port = IntegerField(default=0)

    nick = Attribute(default=None)
    away = BooleanField(default=False)

    channels = ListField("Channel")
    userinfo = ReferenceField("UserInfo")

    registered = BooleanField(default=False)
    signon = DateTimeField(auto_now_add=True)

    @property
    def prefix(self):
        userinfo = self.userinfo
        return joinprefix(self.nick, userinfo.user, userinfo.host)

    class Meta:
        indices = ("id", "nick",)


class UserInfo(Model):

    user = Attribute(default=None)
    host = Attribute(default=None)
    server = Attribute(default=None)
    name = Attribute(default=None)

    def __nonzero__(self):
        return all(x is not None for x in (self.user, self.host, self.name))


class Channel(Model):

    name = Attribute(required=True, unique=True)
    users = ListField("User")

    class Meta:
        indices = ("id", "name",)

This seems to work fine when there is one User and one Channel
object(s) in the database, but as soon as there are two different users
that are members of the same channel I get this error:

I believe Issue #26 is somewhat related?
