In django/db/models/query.py, deepcopy is imported once from copy, and later from django.utils.copycompat. The duplicate was introduced by the multi-db merge (r11952), after the switch had been made to django.utils.copycompat only a few days earlier (r11901).
The copy.deepcopy import is higher in the file, so has no effect, but removing it could help avoid confusion in future.
