SQLCompiler error when using Paginator + values(...) when query returns no data

[Andrew]

I am experiencing a crash in the SQLCompiler when I try to execute a paginated query after calling .values(...).

AttributeError: 'SQLCompiler' object has no attribute 'col_count'

• Postgres 9.3, psycopg2==2.6.1
• Django 1.9
• No data is present in the table

# Query must have NO data returned for it
qs = Room.objects.values('id')
pg = Paginator(per_page=1, object_list=qs)
res = list(pg.page(0))

class Room(models.Model):
    has_tv = models.BooleanField()

I have a fairly minimal reproduction, and can try to reduce it even further (removing DRF, psycopg2, etc) if needed. I don't think it's an issue with postgres. I think it has something to do with the ValuesIterable, but have no way of telling for sure.
