""" 
This comment is program to reproduce the problem. Sorry it's not an 
attachment - as a relative Sourceforge newbie I have no idea how to 
attach to an existing bug. More notes available via email if required - 
including all local variables for each function from post mortem.

As said before, seems to be fp = None. Although the exception is caused 
by the 'self.read = self.fp.read', it looks like 'fp = h.getfile()' inside 
open_http()

This is repeatable, but you may have to run this more than once. 
(Apologies to noaa.gov).

*** PLEASE: Run only where absolutely necessary for reproduction of 
bug!!! ***
