Thanks for the info you provided. I'm using 2.4.1 on cygwin of WinXP. If you want to reproduce the problem, I can send the source to you. This morning I found that this is caused by urllib2. When I use urllib instead of urllib2, it won't crash any more. But the matters is that I want to catch the HTTP 404 Error which is handled by FancyURLopener in urllib.open(). So I can't catch it.
