Received response with content-encoding: gzip, but failed to decode it

```python
import requests

requests.get('http://gett.bike/')
```
This code raises the following exception:
```python
ContentDecodingError: ('Received response with content-encoding: gzip, but failed to decode it.',
error('Error -3 while decompressing data: incorrect data check',))
```
Arch linux x64
requests==2.13.0
python=3.6.0

This seems like the server is returning data it claims is gzipped, but isn't, or is invalid somehow. curl agrees with this assessment, as you can see by doing `curl -L --compressed http://gett.bike`, which leads to:

```curl: (23) Error while processing content unencoding: invalid block type```

You can work around this for now by setting the `Accept-Encoding` header to `identity`:

```python
import requests

requests.get('http://gett.bike/', headers={'Accept-Encoding': 'identity'})
```

But I strongly recommend you reach out to the server operator and get them to fix their server.

I'm now receiving that same error. I've even switched hosting providers. Here's my output. Any ideas?
