Hello, the problem comes from the french translation :
msgid "" "The password you entered is not secure; %s. Are you sure you want to use it?" msgstr "" "Le mot de passe que vous avez saisi est faible.Êtes-vous sûr de vouloir " "quand même l'utiliser ?" There is no %s placeholder in the msgstr regards, Christophe http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=447189
