OK, that's just weird. In my case, the SQL is being correctly converted
to match the "tag_id" column (the equivalent of your "submission_id").
Not sure what's going on there right at the moment.

That should be fixed by using the distinct() method as well:
Blog.objects.filter(entries__blog__id__isnull =
False).distinct()
I hadn't noticed the non-distinct results in my case either, but it
makes sense now that you mention it.
Sorry, I'm not sure why you are seeing the bad SQL being generated; but
at least you have a not-too-painful workaround that gives the same
results. There's a bug in there somewhere. Maybe file a ticket and
somebody will look at it when we have time.
