Bug is still there for me, tested on two machines with latest Feisty yesterday, fresh Beta install and then updated to latest packages. Both machines have 2 ethernet cards, other one is static LAN and other DHCP internet. On both machines, when booting up the DHCP connection is down, and when using Network manager to change configuration, always just one interface at a time works. Either LAN or DHCP, if you enable both at the same time, both interfaces lose their ip and connectivity. Network manager is certainly doing something odd there.
