"Open" popover item on selected sidebar row does nothing

Hence insensitivize or kill.
In nautilus 'open', 'open in a new tab' and 'open in a new window' on the selected row are all insensitivized now, just "open" should have been insensitivized, the other two actually make sense. Not sure it's caused by this, if it's not please move to nautilus.
