Seleniumrc_fu fails with safari

I have seleniumrc_fu working with firefox, but not with Safari. This
appears to be a server side issue as it is complaining about a missing
route for one of the selenium files:

no route found to match “/selenium-server/core/SeleneseRunner.html”
with {:method=>:get}

Is safari supported? Is there additional work / setup needed to test
under safari?
