Thanks Travis,

The error messages on the link seem identical to my issue.

"""dmoz_spider.py"""

import scrapy
class DmozSpider(scrapy.Spider):
    name = "dmoz"
    allowed_domains = ["dmoz.org"]
    start_urls = [
        "http://www.dmoz.org/Computers/Programming/Languages/Python/Books/";,
        "
http://www.dmoz.org/Computers/Programming/Languages/Python/Resources/";
    ]
def parse(self, response):
    filename = response.url.split("/")[-2]
    with open(filename, 'wb') as f:
        f.write(response.body)

Following the official Scrapy tutorial it seems that the spider class 
inherits from scrapy.Spider rather than BaseSpider or CrawlSpider

I am using Twisted 14.0.0 is this OK as I noticed that the Pip download of 
latest Scrapy uses Twisted 10.0.0?
