Comment 17 for bug 39002

To test it:
- run latest dapper live
- when isolinux options appears, choose a language other than english (I always test with Brazilian Portuguese)
- gnome will launch, partly translated.
- Go to menu applications/accessories (acessórios in pt_BR)
- Calculator, for instance, is there, correctly translated as "Calculadora"
- Right-click calculator and choose "Add this launcher to desktop"
- Calculator will appear at desktop, but in english!
- Open a terminal and edit the .desktop file.
- Comment the last line, "X-Ubuntu-Gettext-Domain="
- Now the icon is correctly translated.

This breaks "espresso" icon from being localized, as its icon appears on the desktop.
