    New partition dialog: first filesystem in list is always included
    
    Even if invalid, the first filesystem in list is always included.
    
    This is an off-by-one error, which was triggered when the first member
    of FILESYSTEMS was no longer a regular filesystem, as a result of
    commit ce9feeda0e9a04da04cec0a1b01512ed68c2495c:
    'Make FileSystem objects in GParted_Core accessible and usable by others'
