By any chance, are you using the pipe backend?

I remember having the same problem because my pipe backend script
would return the incorrect record format for a SOA query.

This is the relevant fix in my code, FWIW:

      if ($return_any || $qtype eq 'SOA') {
          if (my $soa_rec = soa_lookup($qname, $config)) {
              # Transform our SOA record in the config to an RR as powerdns  
expects
-            my $soa_rr = [ $qname, $qclass, 'SOA', DEFAULT_SOA_TTL, -1,  
@{ $soa_rec } ];
+            my $soa_str = join ' ', @{ $soa_rec };
+            my $soa_rr = [ $qname, $qclass, 'SOA', DEFAULT_SOA_TTL, -1,  
$soa_str ];
              push @rr, $soa_rr;
          }
      }

Last part of the record was tab-delimited instead of space-delimited
as it should be.
