Package: pdns-recursor 3.5.2-1

When setting pdns-distributes-queries=yes, pdns-recursor crashes when receiving an Dynamic update from one of our zyxels.

Configuration and PCAP-trace already privately shared.

When setting pdns-distributes-queries=no powerdns doesn't crash. Logging changes to "Unable to parse packet from remote UDP client Can't parse non-query packet with opcode=5"

One should mention that this undocumented configuration flag is marked as experimental in code and defaults to "no". As you are using it however i am guessing that you are aware of that but i thought i would clarify this so people using this version of PowerDNS Recursor don't panic about a packet of death that doesn't seem to affect them.
