but didn't help
(i am not that firm with python)

in zope 2.3 the above linked area in DT_In.py looks unfortunately different:
            elif next:
                try:
                    # The following line is a sneaky way to test whether
                    # there are more items, without actually
                    # computing a length:
                    sequence[end]
                    pstart,pend,psize=opt(end+1-overlap,0,
                                          sz,orphan,sequence)
-->             except IndexError:
                    if self.elses: result=render(self.elses, md)
                    else: result=''
                else:
-->                 kw['next-sequence']=1
                    kw['next-sequence-start-index']=pstart-1
                    kw['next-sequence-end-index']=pend-1
                    kw['next-sequence-size']=pend+1-pstart
                    result=render(section,md)
