[Erp5-dev] Site Error List Action

Why there's an error?

       Module Products.ERP5Form.ListBox, line 1633, in query
       1631 |      self.current_page = 0
       1632 |    else:
       1633>|      self.total_pages = int(max(self.total_size - 1, 0) / 
max_lines) + 1
       1634 |      if start >= self.total_size:
       1635 |        start = max(self.total_size - 1, 0)

TypeError: unsupported operand type(s) for /: 'int' and 'NoneType'

where should I set max_lines?
