Comment:
I think this is data-dependant and trying to fix this in 1.5 is impossible
without getting a reproducible test case. Also, this is very likely fixed
in master as `__deepcopy__` isn't used any more for cloning the query.
Backpatching the `__deepcopy__` removal can't be done, it is just too big
of a change and has a real possibility for nasty regressions.
I don't see any other option as to close this as needsinfo. This doesn't
mean at all that we don't trust the issue exists, just that there is no
way to fix this unless we can reproduce the issue.
