I think I see what's happening here. Here's what `DictReader` does if one of the lines has too many items in it:

```pycon
>>> import csv, io
>>> list(csv.DictReader(io.StringIO(""id,name\n1,Cleo,nohead\n2,Barry"")))
[{'id': '1', 'name': 'Cleo', None: ['nohead']}, {'id': '2', 'name': 'Barry'}]
```
See how that row with too many items gets this:
`[{'id': '1', 'name': 'Cleo', None: ['nohead']}`

That's a `None` for the key and (weirdly) a list containing the single item for the value!
