[Andre Schubert]

Hi,

i have found a solution in DT_In.py
change this( beginning at line 537 ):

                    else:
                        kw['previous-sequence']=0
                        if index==last:
                            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)
                                kw['previous-sequence']=0
                                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
                            except: pass

to this:

                    if index==last:
                        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)
                            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
                        except: pass

and everything works well with size=1
