Twisted Web Proxy Help!

I wrote a Twisted Python HTTP proxy, and keep getting the following Traceback after navigating to a page through the proxy.

Traceback (most recent call last):

 was lost; use Request.notifyFinish to keep track of this.

What does this mean? How do I fix it? Is it a module problem, or a problem in my code? I am on Windows XP using Python 2.6

This is a known bug in twisted.web.proxy. It's typically harmless. If it's causing problems for you, please consider contributing a patch to fix it!
