Comment (by mikeperry):

 FWIW, I am unable to reproduce this. I installed nscd on an Ubuntu 14.04
 machine, restarted Tor Browser, browsed with tcpdump watching port 53, and
 saw no DNS leaks.

 I suspect that the answer on https://tor.stackexchange.com/questions/4350
 /tor-dns-cached is right. Probably nscd cached an earlier non-TBB DNS
 query for something, and was refreshing it because the TTL expired, or for
 other reasons unrelated to TBB activity.
