Django Development Server Question

I noticed that when I am developing a Django App in debug mode, I sometimes see this output on my server stdout:

Traceback (most recent call last):
  File "/Users/josephmisiti/projects/temp/lib/python2.6/site-packages/django/core/servers/basehttp.py", line 284, in run
    self.finish_response()
  File "/Users/josephmisiti/projects/temp/lib/python2.6/site-packages/django/core/servers/basehttp.py", line 324, in finish_response
    self.write(data)

    self._sock.sendall(buffer)
error: [Errno 32] Broken pipe
[27/Aug/2011 11:54:14] "GET / HTTP/1.1" 2

Can someone tell me why this is happening?

The browser closed the socket connection before the server could finish sending the response (e.g. you closed the tab before it loaded all the way). Don't worry about it.
