Error: HPE_CB_headers_complete

I'm initilializing knox with the same key/secret/bucket that works with another library.

Then I get an object (5 bytes, text/plain) that I know exists in S3:

``` javascript
knox_client.getFile(key, function(err, kres){
if(err) return next(error(500, new Error(err)))
// ...
});
```

And I get an error. Don't know what to do next, but I have a vague suspicion this might be something about HTTPS cert incorrect or something?

```
{ [Error: Parse Error] bytesParsed: 0, code: 'HPE_CB_headers_complete' }

I worked around this by adding secure=false to my client, but I'd prefer to use a secure client. Is this perhaps caused by SSL certs being wrong in my vagrant box 3.13.0-45-generic ?

The report names the caller in /vagrant/MY_CODE.js and a Node _http_client.js stack frame; start by reproducing getFile with secure=true and comparing the endpoint and certificate behavior with secure=false. Done means identifying a repository-level cause and confirming secure-client behavior, but the issue supplies no Knox source file or test to target.
