Due to delete_expired using raw_delete, which apparently doesn't do cascade deletion, models like ExtraTaskInfo aren't deleted and instead an error is raised: update or delete on table "django_celery_results_taskresult" violates foreign key constraint.
For a full error log and example in a real application see this AlekSIS issue.
