You learn something new every day:

"D-Bus interface to the ISC DHCP client

dhcdbd provides a D-Bus interface to dhclient, the DHCP client from
ISC, so applications such as NetworkManager can query and control
dhclient. This allows an application-neutral interface for such
operations."

Whether the messages you are seeing are significant or fatal is unknown to me.

FWIW I have seen windows do this too. Spent a frustrating hour or two
recently getting a friend's teenager's wireless going. Ended up
deleting all the settings and starting from scratch. The same seems to
often be the way with network manager.

Other alternative? set up a /etc/network/interfaces file for each
location and have a script to swap tham over and do
/etc/init.d/network restart

(PS check those filenames, I am working from alzheimers).
