Duplicated entries in "Open with other applications"
In nautilus, right-clik on a file > Open with other applications > View all applications As a result, some applications are listed duplicated (example: marble, rhythmbox, ...) - see printscreens:
Reason seems to be that several .desktop files are installed by these applications in /usr/share/applications/ Examples:
/usr/share/application/rhythmbox.desktop /usr/share/application/rhythmbox-device.desktop (*) /usr/share/application/marble_geo.desktop (*) /usr/share/application/marble_geojson.desktop (*) /usr/share/application/marble_gpx.desktop (*) ... /usr/share/application/org.kde.marble.desktop
In some of these files (files with (*) above), the line "NoDisplay=true" is written -> maybe should used not to add an entry in the menu ?
