I ran into the same problem and can also confirm that this is a problem 
with dell's nameserver or a system on dell's side. Further 
investigation with ethereal showed that matching pakets had their udp 
crc set to 0x0000. My questions are: 

Should this condition really considered harmful and matched by unclean?
Why is there no corresponding log message from the unclean module?
