Extremely strange problem with httplib/urllib

[Gustaf Liljegren]

Python 2.1 on Win98SE:

I have got some experience with httplib and urllib by now, but suddenly 
both are causing "invalid page fault" errors in Windows. Here's all I need 
to do:

import urllib
f = urllib.urlopen('http://www.google.com')

And the nasty error looks like this:

PYTHON caused an invalid page fault in
module KERNEL32.DLL at 017f:bff7b992.

Same thing happens with httplib, and it doesn't the web page. I have 
reinstalled Python, restarted the computer, and re-established connections, 
but I still have it! It seems like the code is always run to the last line, 
then this happens.

Also, if I write the above script in Idle or on the command line, this 
error don't appear. It's no first time problem -- I have used these modules 
extensively before. Any ideas?
