Comment (by srkunze):
> I believe this to be another instance of the "multiple multivalued joins
in the same query produces wrong results for aggregation" problem. I wish
there was an easy solution for this.
I remember we having this issue as well in 3 of our products using Django.
We solved it by using Python for loops and dicts created from values_list.
Not sure if swapping filter and annotate would have helped there.
What I can tell you and what I remember is that it's definitely not
intuitive. ;-)
