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')
>>> b = Person(name='Bill')
>>> c = Person(name='Chuck')
>>> d = Person(name='David')
>>> a.friends.add(b,c)
>>> d.friends.add(a,c)
>>> a.friends.all()
Traceback (most recent call last):
  File "<console>", line 1, in ?
  File "/sw/lib/python2.3/site-packages/Django-0.95-py2.3.egg/django/db/models/", line 101, in __repr__
    return repr(self._get_data())
  File "/sw/lib/python2.3/site-packages/Django-0.95-py2.3.egg/django/db/models/", line 444, in _get_data
    self._result_cache = list(self.iterator())
  File "/sw/lib/python2.3/site-packages/Django-0.95-py2.3.egg/django/db/models/", line 177, in iterator
    select, sql, params = self._get_sql_clause()
  File "/sw/lib/python2.3/site-packages/Django-0.95-py2.3.egg/django/db/models/", line 458, in _get_sql_clause
    joins2, where2, params2 = self._filters.get_sql(opts)
  File "/sw/lib/python2.3/site-packages/Django-0.95-py2.3.egg/django/db/models/", line 618, in get_sql
    joins2, where2, params2 = val.get_sql(opts)
  File "/sw/lib/python2.3/site-packages/Django-0.95-py2.3.egg/django/db/models/", line 669, in get_sql
    return parse_lookup(self.kwargs.items(), opts)
  File "/sw/lib/python2.3/site-packages/Django-0.95-py2.3.egg/django/db/models/", line 789, in parse_lookup
    joins2, where2, params2 = lookup_inner(path, lookup_type, value, opts, opts.db_table, None)
  File "/sw/lib/python2.3/site-packages/Django-0.95-py2.3.egg/django/db/models/", line 890, in lookup_inner
    raise TypeError, "Cannot resolve keyword '%s' into field" % name
TypeError: Cannot resolve keyword 'person' into field

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!
