I think it should look like the shortcut of firefox

Actions=NewWindow;NewPrivateWindow;

[Desktop Action NewWindow]
Name=Open a New Window
Name[fr]=Ouvrir une nouvelle fenêtre
Exec=firefox -new-window
OnlyShowIn=Unity;

[Desktop Action NewPrivateWindow]
Name=Open a New Private Window
Name[fr]=Ouvrir une nouvelle fenêtre de navigation privée
Exec=firefox -private-window
OnlyShowIn=Unity;

i have removed some of language for little description

After a fresh install of Ubuntu 14.04 or after a purge and reinstall of Libreoffice + libreoffice l10n-fr
Nothing change
