I think I have this bug as well. I upgraded from 8.04 to 8.10. I had a static IP wired connection under 8.04 which worked but this stopped working after upgrading to 8.10.

I followed advice from messages above and set

[ifupdown]
managed=true

In my /etc/NetworkManager/nm-system-settings.conf file which allowed me to select a wired connection under NetworkManager, but still I didn't have an internet connection.

When I commented out the line:
iface eth0 inet static
and added auto eth0
in my /etc/network/interfaces file I can at least connect through my wired connection using DHCP but putting in a static IP address still won't work.

Something that I have noticed though which I think is odd:
When I set my wired connection to use a static IP address, I can't use Firefox to open any websites BUT I am able to ping my IP address and connect via ssh from another machine. So I guess this suggests that it's just outgoing traffic that doesn't work when I use my static IP settings.
