This appears to be the problem - your glibc resolver is contacting
those nameservers directly, and they are possibly returning AAAA
records before A records for the NS or name you are looking up -
sending us the tcpdump log may be helpful in diagnosing the 
glibc resolver problem.

NetworkManager(NM) is meant to use named in caching-nameserver mode, 
and to write ONLY the line: 
'nameserver 127.0.0.1
'
to /etc/resolv.conf .

It appears that this aspect of NM is not working correctly at the moment -
the NM maintainer has been informed and is working on a solution.

Meanwhile, if you remove the nameservers from /etc/resolv.conf:
$ sed -i '/nameserver/d' /etc/resolv.conf
and start named:
$ service named start

The timeouts should disappear.
