nm-applet.desktop currently contains: OnlyShowIn=GNOME;XFCE; Please remove it (or add KDE). This would make it more functional under KDE, which currently lacks a working NetworkManager gui/client for F-8 (ie, knetworkmanager still doesn't work). We've worked around this for the kde-live spin, but users of other spins should be able to use it too.
Is this still needed since knetworkmanager calls nm-applet in a temporarely workaround directly?
should be fixed already for a while.
