`item.find(p)` returns either an `ElementTree.Element` or `None`. The [lambda on line 24][lambda] coerces the return value to a bool, which is `False` if the `<link>` element has no children (see [`ElementTree.py` line 207][etbooldef]), so the lambda returns `None`. Further, returning a `Link` with `url=None` violates [an assertion in `index/schema.py`][assertion], which crashes the `archivebox add` command.
