Comment (by cessor): Replying to [comment:2 Mariusz Felisiak]: > I'm really puzzled. I cannot reproduce this issue manually, but `make red` crashes. Thank you for giving this a try. I investigated this some further and realized that my manual description is not precise enough to reproduce the error. The example I attached uses a SlugField, but the error does not occur with other field types, such as CharFields. I noticed that SlugFields set `db_index=True` by default (See Link 1), and could reproduce the bug with other fields when setting `db_index=True`. I will change the bug description accordingly.
