This is because the original version is no longer in development, as stated on the website at http://code.google.com/p/partiwm/wiki/xpra: "This project is in deep hibernation; I haven't had time to devote for several years now. If you are looking for xpra, you may prefer Antoine Martin's fork, which receives more support. It is available at: http://xpra.org/" So I guess its safe to switch over to that fork.
