This problem occurs, when you have multiple network interfaces, and one is
configured (to use a static ip) via /etc/network/interfaces.
NM will ignore this interface, but as there are other network interfaces, it
will manage these interfaces and try to establish a connection via one of them.
If dhcp fails for that interface, it tries to get a LinkLocal IP address and
/etc/resolv.conf is overwritten with an empty file.

Ubuntu has a patch, which treats interfaces defined via /etc/network/interfaces
as "always up" and ignores them too. A better solution obviously is, to make NM
also understand a static configuration, so it can manage such interfaces.

The next major release, 0.7 is said to bring support for static configurations
natively, As a workaround for now, you can disable the other network interfaces
in your system for NM, by specifying them in /etc/network/interfaces until a
better solution is found.
nm-tool will list all interfaces in you system. If you add entries like

iface ethX inet manual

NM, will ignore them.

Why is it that all of the instruments seeking intelligent life in the
universe are pointed away from Earth?
