can only resolve dns names as root or with explicit nameserver address

[Kelly Clowers <kelly.clowers@gmail.com>]

Using Sid here, I suddenly cannot resolve DNS names normally. My web
browsers, ping and dig do not work with names (ping works with an ip
address), but sudo ping and sudo aptitude resolve normally and dig
works as my user if I give it the ip address of the nameserver (e.g.
dig @192.168.1.1 cnn.com). I am really confused by this one. Any
ideas?
