New submission from Jean-Marc Le Peuvedic <lepeuve...@gmail.com>:
When running the built-in web server of web.py, the following error messages
appear when the HTTP client fetches a non existing CSS file:
TypeError('WSGI response header value 469 is not of type str.',)
Traceback (most recent call last):
File

TypeError: WSGI response header value 469 is not of type str.
The faulty header is added by Python library, http/server.py.
Error added in version 3.4 according to comments.
Lines 467-471 in the attached file:
body = content.encode('UTF-8', 'replace')
self.send_header("Content-Type", self.error_content_type)
self.send_header('Content-Length', int(len(body)))
self.end_headers()
The value for 'Content-Length' is passed as an 'int', but only a 'str' is
acceptable.
In the latest revision of 'server.py', the same code appears line 453.
A possible correction is :
body = content.encode('UTF-8', 'replace')
self.send_header("Content-Type", self.error_content_type)
self.send_header('Content-Length', str(int(len(body))))
self.end_headers()
