after I did update all my CentOS6 boxes - VMs and router; two of them 
(one VM and the router) are my local DNS resolvers;
and I'm using the DNSSECTLSAvalidator plugin from nic.cz: 

before the update this plugin worked using my resolvers, after the 
update I get:
"Failure - bogus DNSSEC reply, DNSSEC validation not possible with 
current settings"
of course, when telling using a custom resolver (the one of nic.cz) it 
works, but before mine worked, too ...
