The following program works fine under Mac OS 10.5.x. But in 10.6, it 
crashes Python, and displays Apple's crash reporter dialog. I've tried 
it on Python 2.6 and 2.5, both the 64-bit and 32-bit versions.

The crash seems to happen any time urllib.urlopen is done in a thread. 
The same thing happens if I do it in a BaseHTTPServer.HTTPServer, using 
SocketServer.ThreadingMixIn.


#!/usr/bin/python
import threading, urllib

class MyThread (threading.Thread):
	def run(self):
		c = urllib.urlopen("http://www.google.com")

MyThread().start()
