Isn't it more likely it's a local problem?

Which version of bind are you running? Does *any* zone validate e.g. try:

dig +dnssec @localhost www.ic.ac.uk

...and you should see:

; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 18199
;; flags: qr rd ra ad; QUERY: 1, ANSWER: 2, AUTHORITY: 8, ADDITIONAL: 11

Note the "ad" flag - "authenticated data".
