BIND is trying to prove that there is a valid secure -> insecure
transition. It has found a cached NXDOMAIN response that has not been
validated. The comment above the logger call says:

        /*
         * This shouldn't happen, since the negative
         * response should have been validated.  Since
         * there's no way of validating existing
         * negative response blobs, give up.
         */
