you can check this, when you do:
host -c chaos -t txt version.bind your.secondary.nameserver.tld


host:/home/foo# host -c chaos -t txt version.bind ns2.wavecon.de
;; Warning: Message parser reports malformed message packet.
Using domain server:
Name: ns2.wavecon.de

version.bind text "Served by POWERDNS 2.9.16 $Id: packethandler.cc,v 
1.24 2004/02/08 10:43:50 ahu Exp $"

this only works, when it is not faked by the admin.

can you paste the complete error message of the server? and, maybe, the 
complete pdns.conf. What Backend do you use? Can you show some dumps of 
the Domain? (master and - if possible - slave)
