Comment 6 for bug 289466

OK, this is somewhat a feature. Most likely all devices are in
/etc/network/interfaces, which basically means that NM doesnt have a
single device to manage and thus doesnt display the applet.

I admit that this is a confusing thing, but having an applet that
doesnt allow you to do anything wouldnt be less confusing.

Remove your configurations from /etc/network/interfaces if you want to
use NetworkManager ... otherwise just manage your network using
ifup/ifdown command line tools (which doesnt require the applet at
all).
