most (all?) of the bugs labeled as duplicates of this one are reporting a related issue, but not exactly the same one. This bug seems to be that the "show menu bar" options makes no sense in an environment such as unity and so should be hidden. The duplicates are about environments such as gnome-shell where there is no global menu bar. In that case the "show menu bar" option is broken, which I would think is significantly more annoying but probably affects fewer users (though I count myself among their ranks). I leave it to the maintainers to decide if these are really the same bug.
