Problem with bbtest-net using ARES

[Francesco Duranti]

I've created yesterday a local DNS on the hobbit server using bind that
is working as slave for the Microsoft AD DNS so that I can use it
without having the problem that a DNS/Network fault will not let hobbit
resolve the name.

To test i used this command and it crash without "--no-ares" :
bbtest-net --debug --report --ping --checkresponse --dnslog=/tmp/pippo
--no-update 

After I started to use this local DNS bbtest-net started to crash during
the name resolution. Now it's working with --no-ares
