Python django模板url标记导致超过最大递归错误

我使用django 1.5.1和django social auth进行社交登录。要获取facebook登录url，我使用

from django.template import Template, Context 
facebook_url = Template("{% url 'socialauth_begin' 'facebook' %}").render(Context())

只得到下面的错误

Template error:
In template <unknown source>, error at line 1
maximum recursion depth exceeded
1 :  {% url 'socialauth_begin' 'facebook' %} 

模板错误：
在模板中，第1行出现错误
超过最大递归深度
1:{%url'socialauth_begin''facebook%}

它在我的生产服务器和本地dev-box上运行良好，python、django和django social auth版本似乎相同。我试图弄清楚某个库的语法是否发生了变化，在我的测试服务器上，该库的版本可能不同
