Comment 14 for bug 742967

Yes lupin-support is installed. I believe that's always included with wubi - you could previously prevent it by hitting the skip button during the ubiquity install (bug 620028), but the latest ubiquity doesn't have a skip button (that I've noticed). I've got version 0.33 installed.
