Django Unprintable TemplatesyntaxError对象由urlconf引起?

我正试图建立一个Django项目,而我的URLCONF似乎有问题。我不确定这是什么交易,下面的错误对我没有完全的帮助。实际上,我认为它与模板呈现没有任何关系,因为我一直在执行路径中执行,直到渲染响应函数完成(在这个过程中,urlconf似乎导致了一个错误),模板对象被正确解析。

这是我的顶级URLCONF:

from django.conf.urls.defaults import *

urlpatterns = patterns('',
   (r'', include('pub.urls')),
)

和酒吧:

from django.conf.urls.defaults import *
import pub

urlpatterns = patterns('pub.views',
    (r'^$', 'index')
)

和pub.views.index:

# Create your views here.
from django.shortcuts import render_to_response
from django.http import HttpResponse
import openidgae

# this needs to be moved somewhere else, but for now it can live here
def index(request):
    lip = openidgae.get_current_person(request, HttpResponse())
    resp = render_to_response('pub/index.html', {'lip': lip}) # exception thrown here
    return resp
