nodegit: 5.6.0 https url: [Error: HTTP parser error: unexpected content-length header]

With node 5.6.0 which fixes https parsing errors and changes current parsing behavior (https://nodejs.org/en/blog/vulnerability/february-2016-security-releases) trying to git clone or rebase https bitbucket private url results in

[Error: HTTP parser error: unexpected content-length header]

standard clone example will reproduce this error

 nodegit.Clone(
// basic auth bitbucket repo is what I was testing
    "https://user:pass@bitbucket.org/repo.git",
    path,
    {
      fetchOpts: {
        callbacks: {
          certificateCheck: function() {
            // github will fail cert check on some OSX machines
            // this overrides that check
            return 1;
          }
        }
      }
    })

node 5.5.0 works as expected

this seems like an error from http-parser itself so I don’t know if this is really related to nodegit, since I’m very short on time to do some more debugging
