code: def test_modify_paths_bug(tmpdir):
      """
      There was a bug in which, if the current working directory contained a file with the name
      of an output String, the string would get transformed into a path, and generally wreak havoc.
      This attempts to replicate that condition, using an object with strings and paths in various
      trait configurations, to ensure that the guards added resolve the issue.
      Please see https://github.com/nipy/nipype/issues/2944 for more details.
