10045	bug in aggregations: .annotate() followed by .filter() on related field breaks	alex@…		"I get something that looks like a missing join condition when doing 

{{{ModelA.objects.all().annotate(num_b=Count('modelb')).filter(modelb__somebool=True)[0].num_b}}}

I get {{{num_b = 2^i}}} for i objects of ModelB instead of {{{num_b=i}}} as I would expect to. 
Please see attached models.py file for the Model definition and test case.
