Right, that's a Python feature.

The cause of the problem seems to be that DateTime() constructor
expects integers as argument and that the code in RelativeDateTime
can generate floats as a result of refitting the values into proper
ranges.

Try adding this snippet in DateTime.py before line 585:

             # Refit into proper ranges:
             if month < 1 or month > 12:
                 month = month - 1
                 yeardelta, monthdelta = divmod(month, 12)
                 year = year + yeardelta
                 month = monthdelta + 1

             # Make sure we have integers
             year = int(year)
             month = int(month)
             day = int(day)

             if self.weekday is None:
                 return DateTime(year, month, 1) + \
                        DateTimeDelta(day-1,hour,minute,second)
