    baobab-scan: workaround bugzilla bug 672219
    
    After recent gio changes, on some filesystems (namely NTFS) a symlink
    to a directory is reported by GFileEnumerator as a normal directory.
    This can generate infinite loops if there is a symlink to .. somewhere.
    
    Since this only affects GFileEnumerator and not g_file_query_info(),
    workaround this issue using the latter.
