Found via Zombie images database report:
$ sql --cluster web commonswiki 'SELECT 1 FROM commonswiki_p.image WHERE img_name = "Stuttgart_train_station..jpg"' +---+ | 1 | +---+ | 1 | +---+
This should be empty as in production.
Update from T179767#3735491
Same for the other zombie file:
SELECT * FROM image WHERE img_name = "Is-sur-Tille_Motocross_finale_du_championnat_de_France_féminin_2015_-_Erell_BOULOUARD-12.jpg"\G
