Django-paging unhashable type

paginators.py (django-paging package):

try:

_page = EndlessPage(list(self.object_list[bottom:top]), number, self) 

this line gives an error of type TypeError: unhashable, although this object_list comes from the standard QuerySet, which can be used with [bottom: top] without any problems.

template:

{% with paginate(request, my_queryset) as results %}
{{ results.paging }}
    {% for result in results.objects %}
        {{ result }}
    {% endfor %}
{{ results.paging }}
{% endwith %}`

View:

my_objects = BetterPaginator(queryset,25)
page = 1
context = { 'my_queryset': my_objects.get_context(page) }
