            fileHistory = codecs.open(os.path.join(env['GISDBASE'],
                                                   env['LOCATION_NAME'],
                                                   env['MAPSET'],
                                                   '.bash_history'),
                                      encoding = 'utf-8', mode = 'r')

This will result in the problem you describe if the .bash_history file
contains any non-UTF-8 data, which is a definite possibility
regardless of the user's locale settings.

I suggest adding errors='replace' or errors='ignore' when calling
codecs.open().
