Okay I have finally figured out the workaround for NetworkManager 0.7.0 in Ubuntu/Debian.
NetworkManager should be looking at "/etc/dhcp3/dhclient.conf", but it's not. It seems to be looking for /etc/dhclient-eth0.conf or /etc/dhclient-wlan0.conf.
For example if your interface is eth0 here is how you'd fix it.
sudo cp /etc/dhcp3/dhclient.conf /etc/dhclient-eth0.conf
