Feed has a 302 redirect but feedparser throws AttributeError: 'NoneType' object has no attribute 'status'

This feed is not actually a feed but rather a 302 redirect. But the 302 is missing the Location header which would then be used by feed parser. Instead, we get an AttributeError:

>>> import feedparser
>>> fp = feedparser.parse('http://tools.microformatic.com/transcode/rss/hatom/http://fusesource.com')
Traceback (most recent call last):

    result.status = code

Here's the feed headers:

Should feedparser be able to handle a broken feed that's broken like this?

Well, requests doesn't choke on it, probably feedparser shouldn't either. I'll see what I can do!

Samuel, this should be fixed in feedparser 6.0.6. Thanks for reporting this!
