Thanks for your bug report, unfortunately Notification Area is deprecated and all Ubuntu apps are being ported to use application indicators. Both Unity and GNOME Shell are also getting rid of Notification Area.
NM-applet should work out of the box as it has nm-applet-use-indicator.patch when built on Ubuntu. There is a third-party indicator available for Pidgin, as well.
So if you really want to use Notification Area, you'll have to add it manually.
