If you are using network-manager, you need to comment the final line as

#iface eth0 inet dhcp

network-manager does all the work, so other than the lo (loopback)
( which looks right), you don't need anything else
in /etc/network/interfaces

After commenting that last line out, rerun

sudo /etc/init.d/dbus restart   

See if that works for you ... if the applet fails to start after
restarting dbus, you can start it with

nm-applet &   

(but that shouldn't be necessary with the latest
network-manager-gnome )
