Comment 4 for bug 1070581

Much like bug 991002, this is a situation where Ubuntu would not enjoy getting ahead of its upstream (in this case, glibc). I've filed a bug and will file a patch (attributed to you) with them: http://sourceware.org/bugzilla/show_bug.cgi?id=14925

Once they fix it upstream, Ubuntu will have to sync that localedata into langpack-locales.
