I have no data, whether same problem exists on a regular Ubuntu, Debian or any other kind of distro with the UI of this application, however in my special install case, it goes like this: "gtk-hinzufügen", "gtk-löschen", "gtk-verbinden", "gtk-über" and "gtk-beenden". Yes, it's the German localization, thus can be a problem with i18n e.g. because the application is not translated correctly into German at all. The whole thing doesn't really bother or disturb me, or interrupt the usefulness of the program in any way, however, it would be nice just to see "Hinzufügen", "Löschen", "Verbinden", "Über" and "Beenden" on that buttons (and on all other, as soon as the connection's established) instead the way it shows up right now. Thanks in advance!
The same in ubuntu and its not a translation problem.
