        Depends on: 22440

We stumbled upon this on one of our upgrades.
This is what I think happened:
Because bug 22440 is also the one introducing cascade delete on biblio_id in
illrequests table, in the past, when a biblio was deleted its id still remained
in the biblio_id column of illrequests.
This causes the API embed to respond with a biblio_id for the ILL request, but
a null biblio (because it wasn't able to retrieve it, it doesn't exist).
