e dbusmenu - fix cross referencing from e menus created from debus menu 

this stops crashes when e menu si still up when the dbus menu backing
it has changed/gone away... by referencing the dbusmenu to hang about
like a bad smell while the e gui menu is up until it's dismissed. this
fixes a real segv i saw with steam.
