RepositoryCommit fails, type cast error

[madisona]

Similar to #124

import 'dart:async';
import 'package:github/server.dart';

void main() async {
  GitHub github =
      createGitHubClient(auth: new Authentication.withToken(myToken));
  RepositorySlug slug = RepositorySlug("flutter", "flutter");
  Stream<RepositoryCommit> commitResults =
      github.repositories.listCommits(slug);

  await for (RepositoryCommit commit in commitResults) {
    print(commit.commit.message);
  }
}

gives:

$ ./bin/github_bug.dart 
Unhandled exception:
