This will work during pickle.dumps: http://paste.pocoo.org/show/278047/
but will fail when I run loads.
The reason is that {{{ __getstate__ }}} of {{{ ValueQueryset }}} puts (in
this case) {{{ ['name', 'deleted', 'id', 'id'] }}} into {{{
obj_dict['search_fields'] }}}
(http://code.djangoproject.com/browser/django/trunk/django/db/models/sql/query.py#L176);
during loads it won't find Page.deleted etc… (full traceback:

Comment (by Alex):
Cleaned up the formatting.
