I think I may have found a bug. I stepped though the code, and
values_list() does want to respect any extras that may have been
added. In django/db/models/query.py(962)_setup_query() it does:

if not self.query.extra and not self.query.aggregates:

And for my case that is returning false, but I do have extras:

(Pdb) print not self.query.extra
False
(Pdb) print self.query.extra
{'top-bottom': (u'top-bottom', [])}


This does not seem correct to me. Am I missing something here (because
I've been coding since 4:30am and it's 8pm now)?
