Agreed. This looks like a bug to me; at a guess, the problem will be
that when ValuesQuerySet is cloned, it doesn't copy the attribute list.
It may be worth checking if this is still a problem with queryset-
refactor; if it is stil a problem, it might be better to fix the
problem there, rather than trunk.
