Mark, I tried to follow those instructions, but the awn-manager refused to allow any deletion of those applets. All it says is: "Unable to delete applet". At first I did it without use of sudo, which in terminal window outputs this while launching awn-manager from the terminal window and removing the phantom launchers:

/usr/bin/awn-manager:68: GtkWarning: GtkSpinButton: setting an adjustment with non-zero page size is deprecated
  self.wTree = gtk.glade.XML(self.GLADE_PATH, domain=defs.I18N_DOMAIN)

(awn-manager:14506): GConf-WARNING **: Directory `/apps/avant-window-navigator/applets/-71792140_1232572988' was not being monitored by GConfClient 0xa50e750
/usr/bin/awn-manager:213: Warning: invalid uninstantiatable type `(null)' in cast to `AwnConfigClient'
  gtk.main()

Then if I simply try to run it with sudo I get this instead and cannot launch the awn-manager at all:

/usr/bin/awn-manager:68: GtkWarning: GtkSpinButton: setting an adjustment with non-zero page size is deprecated
  self.wTree = gtk.glade.XML(self.GLADE_PATH, domain=defs.I18N_DOMAIN)

I'm not even using KDE, but rather GNOME in Ubuntu Intrepid, so I don't know what's the whole fuss about desktop session starting in KDE.
