The userpasswd program in usermode seems to be only be wrapping the output of the passwd program in a GTK window. This means that userpasswd isn't really translateable, since passwd isn't translateable. :( In the future, I'd thus really like to see a translateable "passwd" with gettext support.
A translatable passwd command also requires translatable modules in PAM, which is going to affect several packages....
In that case I guess my translation request will cover those modules too... :-)
Christian, could you please file a bug against pam regarding the issue? Passwd actually calls pam and libuser for user authentication, so the messages need to be translated there.
Ok, added bug 143873.
