To reproduce the error start Python 3.0 and enter the usual WSGI "hello
world" application:

>>> from wsgiref.simple_server import make_server, demo_app
>>> httpd = make_server('', 8000, demo_app)
>>> httpd.serve_forever()

Open a browser and point it at http://location:8000/. On each HTTP
request an exception will be thrown:

----------------------------------------
Exception happened during processing of request from ('127.0.0.1', 55779)
Traceback (most recent call last):

----------------------------------------

Expected result: The nice demo page containing WSGI environment
variables is displayed in the browser.
