Public bug reported:
Binary package hint: dhcdbd
After installing NetworkManager it detects ethernet cable and wireless
networks. But when registering in the network, NetworkManager fails to
receive IP from DHCP server.
Here is the part of /var/log/syslog:

As you see, dhclient detects IP correctly (172.16.0.12), but
NetworkManager fails to accept this IP and uses 169.254.108.117 instead.
This results in non-working network connection, so I have to manually
run dhclient and get a correct IP.
