Django 1.5.2在自定义上下文处理器内使用resolve调试false会导致服务器错误

我有一个自定义的上下文处理器。我将在每个请求中获得url_名称，以便全局传递到模板

def custom_context_processor(request=None, sender=None, **kwargs):
    url_name = resolve(request.path).url_name
    .....

调试模式为真时，一切正常。但当它设置为False时，我得到500个服务器错误

在测试了一段时间后，我发现i18n url模式无法使用debug=False

例如，如果我写localhost/it，它不会重定向到默认语言localhost/en

但是，如果我编写localhost/en django，则不会出现错误，并且可以按预期工作

在settings.py中，我有：

ALLOWED_HOSTS = ['*']

我在templates文件夹中有404.html和500.html错误页

在Django中启用错误日志时，我得到：
