This bug involved unbound failing to resolve at all nameservers, and then trying to get the parental-delegation information. This is great to resolve troublesome names normally, but when a configuration entry is present, this is not supposed to happen. The issue was code in iterator/iterator.c:can_have_last_resort() which was fixed for this issue (commit r2882).
