found out, that pdns replies with SERVFAIL.  dig +nofail works.
RFC 1035 [1] states, that "Server failure" indicates:
The name server was unable to process this query due to a problem with
the name server.
The only other alternative for pdns would be:
No error condition.
and sending an empty reply.
Some googling reveils, that this case is a correct use of SERVFAIL.
Just unfortunate that dig does not use +nofail by default (which I
expected by reading the first paragraphs of its man-page)

SERVFAIL seems to be a good / correct answer, so END seems to be fine.
