you don't get it by choosing to install zeitgeist, it comes in as a dependency of unity-place-files and unity-place-applications, which are recommended dependencies of unity. Remove zeitgeist and you lose the unity place things too.

Oh btw, getting this issue on x64 desktop too. reports i've seen so far seemed to all be for x86 so thought i'd mention...
