The whoops-silex from texthtml

Identifier "dispatcher_class" is not defined

Hi,

When trying to use this with Silex 2.0 I'm seeing this error:

JsonResponseHandler returns text/html header?

Not sure if this is an issue with Whoops or Silex+Whoops.

I use the JsonResponseHandler:

$app->register(new WhoopsSilex\WhoopsServiceProvider());
$app['whoops']->pushHandler(new Whoops\Handler\JsonResponseHandler);

In my response I get this header though:

Content-Type:text/html; charset=UTF-8

As far as I can see, Whoops is trying to do the right thing:

https://github.com/filp/whoops/blob/master/src/Whoops/Handler/JsonResponseHandler.php#L84

It does hit this pathway and add the Content-Type header:

        if (\Whoops\Util\Misc::canSendHeaders()) {
            header('Content-Type: application/json');
        }

And if I put a die before it returns Handler::QUIT then the response does come back with application/json:

        echo json_encode($response);
        die(); # I then see application/json as the header in the output
        return Handler::QUIT;

Any idea how I can diagnose whether this is a bug in Whoops or something that's happening between Whoops/Silex?
