I have the same bug when trying to use hamachi. The hamachi client assigns a static IP, but networkmanager tries to run dhclient on the address which fails. The underlying interface is a tun device which gets a new mac address each time, so saving settings to tell NM to ignore it don't work. Putting the blacklisting line above helps.
