HiPhil, Do you have any plugins installed? I ma quick search and I don't have this ruby (Olmage.rb) on my HD. Also, there's no kml exporter in my exporters folder of SU 7 so I could imagine that this is a plugin that would require a kml exporter. Now if I'm not mistaken, there used to be (???) kml export from older versions of SU (maybe v.5?) so this could even be an old plugin that would like to use that function (but I'm not sure about that since it was some three years ago). I also made quick Google search for "Olmage.rb" but it didn't return any useful.
