[Corey Berla <coreyberla src gnome org>]

commit f600c557649f79f3b992634840b0e267ddf5c92d

    app-chooser: Don't allow changing default on a folder
    
    Nautilus opens folders natively regardless of the default file type.
    Don't allow users to change the default association for a folder
    which would otherwise give a false impression.
