Pino, maybe the Debian GNOME maintainers go a bit too far by blacklisting KDE apps but the KDE maintainers have show no interest in correctly using the NotShowIn=GNOME; values for basic apps like Calculator, System Monitor, etc.
Anyway Ubuntu currently disables that blacklist so I'm going to go ahead and close this bug since it's not a gnome-menus issue in Ubuntu.
