So the other possibility is that "some" firewall/router on the path is 
being helpful and thinks it knows that DNS can only be 512 bytes, so 
this weird thing must be illegal and throw it away. This could be 
anywhere in the path, maybe outside your network, maybe only being used 
some of the time.
