1. Videos on ubu.com are now hosted on Vimeo

The server serves malformed header "Content Type: text/xml" for the XML
request (it should be Content-Type but not Content Type). Python 3.x,

Content-Encoding header is not parsed, so the returned content is kept
not decompressed, and thus XML parsing error.
