if the applet is destroyed, then returnToSource() the extenders. perhaps we should be watching for extenders being deleted at random (QObject::destroyed signal?). also, seems that returnToSource is broken in general atm, but only for items in the panel, though that seems to be a separate issue. i wonder if that's a PopupApplet bug? will need to investigate.
