I confirm it.
Moreover this bug even have an impact on Italian translation.
The currently used icon is gtk-new that is translated as "Nuovo", which is masculine genre, because it refers to "document", "file" etc. but "Printer" and "Class" are feminine genre, so it's wrong.
Using gtk-add we can fix it because it's a verb and it could better describe the "action" of adding a new printer or class.

I'm preparing a patch about this.
