Thanks to GNOME Bugstermind Luis, xml2po got its own Bugzilla product, so any further xml2po bug reports should go there.
(I have some reports already sitting in my inbox: if you reported a bug which I didn't respond to, don't worry, I didn't forget about it, just didn't get to it yet; if you wish, you may report it in Bugzilla anyway, I won't mind, and it won't get lost.)
