Stream and BinaryFileResponse generates error in Chrome

[Schyzophrenic]

Hello,

I run into a pretty odd issue.
I have setup a local adapter, which works fine. I write into it without any issue.

But things get strange when I try to deliver the file through the BinaryFileResponse as Chrome complains about : ERR_CONTENT_LENGTH_MISMATCH

Here is how I ask for the file delivery (full details below);

$response = new BinaryFileResponse('gaufrette://stream/'.$track->getFilename(), 200, $headers, false);

The odd thing is that it works if I call the file directly with

$response = new BinaryFileResponse($streamDir.'/'.$track->getFilename(), 200, $headers, false);

I have checked the Content-length header in the BinaryFileResponse and it seems ok...

I am bit lost here and would appreciate any help on this.

Here is the gaufrette config:

knp_gaufrette:
    adapters:
        stream:
            local:
                directory: "%stream_directory%"
                create: true
    filesystems:
        stream:
            adapter: stream
    stream_wrapper: ~

And here is the code used by my controller to deliver the file:

$streamFileSystem = $this->get('knp_gaufrette.filesystem_map')->get('stream');
$map = StreamWrapper::getFilesystemMap();
$map->set('stream', $streamFileSystem);
StreamWrapper::register();

// We prepare the headers of the response
$headers = array(
    'Content-Type'      => 'audio/mpeg',
    'Pragma'            => 'no-cache',
    'Transfer-Encoding' => 'none',
    'Connection'        => 'close',
    'Accept-Ranges'     => 'none',
);

$response = new BinaryFileResponse('gaufrette://stream/'.$track->getFilename(), 200, $headers, false);

return $response;

Note: I call the url directly, there is no HTML involved in this process.
