Reporter: Juan Carlos Moreno
Linode response has "Content-Encoding: gzip" but plain text body is returned:
Request:
curl -i -X GET -H 'Host: api.linode.com' -H 'Accept-Encoding: gzip,deflate'
--compress
'https://api.linode.com:443/?api_key=*********&api_responseFormat=json&api_action=avail.datacenters'
Response:

Proposed solution (caught IOError exception and continue)
libcloud/common/linode.py
< self.body = self._decompress_response(body=response.read(),
---
> # ECmanaged: Linode hack
> # sends "Content-Encoding: gzip" header but a plain/text response
>
> response_read = response.read()
>
> try:
> self.body = self._decompress_response(body=response_read,

> except IOError:
> self.body = response_read.strip()
