Current dh_translations does cover the X-GNOME-Fullname key already. The only other key that "grep -h X-GNOME /usr/share/applications/*| cut -f1 -d=|sort -u" finds is "X-GNOME-Keywords", but glib does not officially support this key, so we don't translate it via gettext. So I don't think we can strip it before that happens.
