Bug in fwfetcher urlopen response

[bonsairobo]

Here's the offending code:

req = Request(url)
try:
	response = urlopen(req)
except URLError, e:
	if hasattr(e, 'reason'):
		print "Failed to reach download server.  Reason:", e.reason
	elif hasattr(e, 'code'):
		print "The server couldn't fulfill the request.  Error code:", e.code
print "Reading response..."
retval = response.read()

I get UnboundLocalError: local variable 'response' referenced before assignment because the URL timed out.
