That did it, the problem is the weird unbalanced opening square bracket erroneously stuck in their link:
Code:
ValueError: Failed to parse the URL: 'http://[http://fortune.com/2015/10/27/this-walmart-halloween-costume-is-making-people-really-angry/?xid=soc_socialflow_twitter_FORTUNE' with underlying error: Invalid IPv6 URL
I'm not sure what the proper thing to do would be in handling this. Obviously it is easy for a human reader to understand what is intended, but generalizing this into the parser would be quite difficult.
