    window: avoid crash when no dnd items
    
    Sometimes is reported that there are not items as sources.
    That makes nautilus crash trying to iterate betweeen them
    in nautilus_drag_default_drop_action_for_icon.
    Even if the fix should be there, it's a situation that
    shouldn't happen at all, so I leave it as a responsability
    of the caller.
