In Chrome OS we will certainly need to have extensions enabled as we intend to
use ChromeDriver to test bundled extensions. Of course, ChromeOS will also need
to launch Chrome indirectly though the session manager, but I suspect this could
also be a use case for desktop Chrome (the extensions often work on both).

I removed this flag. I accidentally put it in there because I was tired of
external extensions messing things up while I was experimenting locally.

   command.AppendSwitch("enable-logging");
   command.AppendSwitchASCII("logging-level", "1");
   base::ScopedTempDir user_data_dir;
   if (!user_data_dir.CreateUniqueTempDir())
     return Status(kUnknownError, "cannot create temp dir for user data dir");
   command.AppendSwitchPath("user-data-dir", user_data_dir.path());
   command.AppendArg("about:blank");
 
   base::LaunchOptions options;
   base::ProcessHandle process;
   if (!base::LaunchProcess(command, options, &process))
     return Status(kUnknownError, "chrome failed to start");
-  chrome->reset(new ChromeImpl(process, &user_data_dir));
-
+  scoped_ptr<ChromeImpl> chrome_impl(new ChromeImpl(
+      process, context_getter_, &user_data_dir, port));
+  Status status = chrome_impl->Init();
+  if (status.IsError())
+    return status;
+  chrome->reset(chrome_impl.release());
   return Status(kOk);
 }
