Network Manager functionality is changed!
Read about it in /usr/share/doc/network-manager/README.Debian.

In short, if interface is (properly or not) configured in /etc/network/interfaces file, Network Manager will not manage it. If there are no other interfaces for NM to manage, NM thinks that there are no network connections.
You may try to comment out any configuration of eth0 in interfaces file, so network manager picks it up for management.

There is also solution to put NM in managed mode as mentioned in README.Debian.
