Due to the way PolicyKit works, not all the translations can be done in the client tools. The authentication dialogs come from the daemon and thus don’t get translated by the GNOME translation team. The GNOME guys are rocking doing the client stuff, but the daemon remains untranslated.
If you have a spare few minutes (only 88 short strings), please send me a .po file from this pot file. You can see what po files already exist in gitweb. I really appreciate it, thanks.
Richard.
