I really only consider indicator-applet-complete useful for debugging (I use it as such) so I'm not sure how important this is to fix. But, the patch that removes these entries when the session menu applet or FUSA is on the panel is in gnome-panel. That patch would have to have the IndicatorAppletComplete added to it. I'll let the gnome-panel maintainers decide what they want to do there. I'm of mixed mind as I don't expect anyone to really have indicator-applet-complete installed unless they're serious tweekers :)
