Hi, I've noticed that in the current development version, symmetrical
many-to-many relationships can call all() AT MOST one time. Using the
supplied example supplied in the documentation, I get the following:
{{{
>>> from core.models import *
>>> a = Person(name='Anne')
>>> a.save()
>>> b = Person(name='Bill')
>>> b.save()
>>> c = Person(name='Chuck')
>>> c.save()
>>> d = Person(name='David')
>>> d.save()
>>> a.friends.add(b,c)
>>> d.friends.add(a,c)
>>> a.friends.all()
Traceback (most recent call last):
File "<console>", line 1, in ?

This problem does not exist in pre-0.96 Django distributions. As I am a
Django newbie, there's not much I can do, but thanks for taking a look!
