This is a known bug in 3.3: 

Discovered by John J and Robin J, the PowerDNS Recursor did not process
packets that were truncated in mid-record, and also did not act on the
'truncated' (TC) flag in that case. This broke a very small number of
domains, most of them served by very old versions of the PowerDNS
Authoritative Server. Fix in commit 1740.

We will be releasing 3.4 shortly. Meanwhile there is the unreleased version
3.3.1, available on
http://svn.powerdns.com/snapshots/pdns-recursor-3.3.1.tar.bz2 which also
fixes this issue.
