添加django.core.context_processors.request时出现BadHeaderError

Question

当我在我的TEMPLATE_CONTEXT_PROCESSORS中包含django.core.context_processors.request时，除了django admin之外，我无法在我的网站上打开任何页面。

我收到BadHeaderError（标题值不能包含换行符）。

示例视图：

def home(request):
    return render_to_response(
        'index.html',
        {},
        content_type=RequestContext(request)
    )

如果我从模板上下文处理器中删除它，一切都很好。
