Comment 1 for bug 1097240

From http://standards.freedesktop.org/desktop-entry-spec/latest/ar01s05.html:

NoDisplay means "this application exists, but don't display it in the menus"

So we don't show these entries. A case where you might want to have a session with NoDisplay=true is a session that can be used for autologin, but is not allowed to be selected by a user.

Please contact the authors of this file and ask them to remove this line (not sure why it is there).
