Have the problem too. eth0 (which I currently use) is set in /etc/network/interfaces, ath0 (Atheros Wifi card) is not. When starting Gnome, the nm-applet doesn't show up (although the process is running). Restarting /etc/init.d/NetworkManager makes it appear. In the menu, I can choose a Wifi network (with ath0) and it says "device is unmanaged" for wired network (eth0).
Will try to comment the interfaces in /etc/network/interfaces but I'm not sure I should as it was setup by the Server installation (using Intrepid Server and installed ubuntu-desktop to have a GUI).
