Comment (by mrmachine):
The test from the fix already applied also fails in 1.5, but the following
test passes in 1.5 and fails in 1.6 showing that this is a regression.
{{{
def test_query_clone(self):
# Ticket #21643
qs = Experiment.objects.filter(end__lt=F('start') +
datetime.timedelta(hours=1))
qs2 = qs.all()
list(qs)
list(qs2)
}}}
Is it enough to back port the existing commit, or should this new test
also be committed and back ported?
