24047	Cannot combine values_list querysets that do subqueries	Danielle Madeley	nobody	"I have a query like:

{{{
qs1 = object.comments.values_list('author__email', flat=True)
qs2 = object.group.members('email', flat=True)
recipients = qs1 & qs2
}}}


Where author and members are both User objects. This tells me the fields must match to do a combine. If I override the field by doing something hacky like qs1.fields=['email'] it tells me the base classes must match to do a combine."
