Title: BUGFIX: older python version seem to be strict on argument types

urllib2.build_opener = build_opener(*handlers)
Create an opener object from a list of handlers.

The opener will use several default handlers, including support
for HTTP and FTP.

If any of the handlers passed as arguments are subclasses of the
default handlers, the default handlers will not be used.
