[Python-modules-team] Bug#743199: queuelib dependency required

[Kumar Appaiah]

Package: python-scrapy
Version: 0.22.2-1
Severity: grave
X-Debbugs-CC: Vincent Cheng <vcheng at debian.org>

The tutorial example given at
http://doc.scrapy.org/en/0.22/intro/tutorial.html#intro-tutorial
doesn't work. If you do everything up to the "Crawling" section, this
happens:

# scrapy crawl dmoz
/home/kumar/Kumar/Programming/Python/Scrapy/tutorial/tutorial/spiders/dmoz_spider.py:3: ScrapyDeprecationWarning: tutorial.spiders.dmoz_spider.DmozSpider inherits from deprecated class scrapy.spider.BaseSpider, please inherit from scrapy.spider.Spider. (warning only on first subclass, there may be others)
  class DmozSpider(BaseSpider):

Please let me know if I need to provide additional details.

Thanks.
