crash : Can't render headers after they are sent to the client

[sallespromanager]

this is a strange error.

it only happens with a collection, no matter if I define an authToken, or not.

http.js:687
    throw new Error('Can\'t render headers after they are sent to the client.'
          ^

Could you create a repo/gist that shows how to reproduce this error? I'm unable to reproduce it on my end and need more information. Thanks!
