Error when cd to a new directory

Created by: xuhdev

Here's the error messages:

  File "/home/hong/.autojump/bin/autojump", line 410, in <module>
    sys.exit(main(parse_arguments()))
  File "/home/hong/.autojump/bin/autojump", line 367, in main
    save(config, first(add_path(load(config), args.add)))
  File "/home/hong/.autojump/bin/autojump_data.py", line 78, in load
    ifilter(correct_length, imap(parse, f))))
  File "/home/hong/.autojump/bin/autojump_data.py", line 68, in <lambda>
    tupleize = lambda x: (x[1], float(x[0]))
ValueError: invalid literal for float(): 14.14210.0

Could anyone help me with this? Thanks!
