The following will work correctly on Python 2.3.3 but fails 
on Python 2.4

This bug is in httplib.py, and I already submitted patch
900744. I wonder why on Python 2.3 it seems to work though,
it should fail the same way since this bug is also present
in Python 2.3. But it might be some change in urllib2 that
triggers this in Python 2.4 and not in Python 2.3.

I can't reproduce this.

1. On what OS did you observe the failure?

2. Anybody have another example that does still trigger the bug?

I added a testcase mockup attachment at patch #900744:

https://sourceforge.net/support/tracker.php?aid=900744

To reproduce with urllib2, start server.py and then execute:

import urllib2
urllib2.urlopen("http://localhost:8000/").read()

For the record, I observed the problem on Gentoo Linux.

Can somebody close this?  It's fixed on trunk in #900744 .
