我正在使用 Wagtail，一个轻量级的 django CMS。我将 Wagtail 升级到 0.8.6（Django 从 1.6.5 到 1.7.7），我有一个基本上显示新闻对象列表的工具：
http://localhost:8020/news/
它使用 django 的分页器，所以如果我尝试访问下一页：
http://localhost:8020/news/2/
我有一个错误：
ValueError at /news/2/
need more than 1 value to unpack
这是回溯：

知道什么会导致这种情况吗？使用以前的设置 ( wagtail 0.5, Django 1.6.5) 它正在工作。
