which triggers, logically, an exception in feedparser:
AttributeError: object has no attribute 'link'

A tolerant mode for feedparser would greatly help, skipping these bad entries entirely, or tolerating entries with no link, depending on what disrupts the less the feedparser code (the only functional need is to be able to return the other valid entries).

Wrong ticket. The issue was coming from my own downstream code. Sorry for the noise.
