avahi ip even if the network cable is unplugged

[yelo_3 <yelo_3 yahoo it>]

Hello, this is a bug I have now with nm 0.6.5-0ubuntu6

when I load the ethernet card module (tg3) and if the cable is unplugged, network manager thinks that the cable is plugged and the applet icon changes into the "acquiring address" and when the dhcp timeout triggers, avahi-autoip gives me an ip, and creates the interface eth0:avah. Now the icon is changed to the normal one, as if I'm connected via the cable. Connection information is showing that everything is 0.0.0.0.

when I plug the cable I get
Jul 10 10:24:13 yelo3-laptop kernel: [ 1460.812000] tg3: eth0: Link is up at 100 Mbps, full duplex.
Jul 10 10:24:13 yelo3-laptop kernel: [ 1460.812000] tg3: eth0: Flow control is off for TX and off for RX.
Jul 10 10:24:13 yelo3-laptop kernel: [ 1460.816000] ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
Jul 10 10:24:14 yelo3-laptop avahi-daemon[7003]: Registering new address record for fe80::211:2fff:feb5:41dd on eth0.*.

the interface eth0:avah will remain up, until I unplug the cable:
Jul 10 10:25:39 yelo3-laptop NetworkManager: <info>  SWITCH:
terminating current connection 'eth0' because it's no longer valid.
Jul 10 10:25:39 yelo3-laptop NetworkManager: <info>  Deactivating device eth0.

Jul 10 10:25:39 yelo3-laptop avahi-daemon[7003]: Withdrawing address record for fe80::211:2fff:feb5:41dd on eth0.

If I plug in the cable again I finally get my normal connection up and running

I don't know if this bug is only of my distribution, which is ubuntu gutsy, or if it is a kernel module bug and I would like to know if any of you has it too.
