title: Using the console with Selenium Webdriver.Chrome() cause Exceptions
body: <p>I'm using Ubuntu 12.04 with Selenium webdriver 2.38.4, Chromium 37.0 &amp; chromedriver 2.10.
  I run a basic script:</p>
  
  <pre><code>chrome_options = Options()
  driver = webdriver.Chrome(chrome_options=chrome_options,
                                executable_path='/usr/bin/chromedriver')
  driver.get('http://www.google.com')
  </code></pre>
  
  <p>once I start looking around at the console of Chrome the next set of commands I try <code>(driver.title, driver.find_element_by_tag_name('body') )</code> will result with:</p>
  
  <blockquote>
    <p>WebDriverException: Message: u"unknown error: Runtime.evaluate threw
    exception:
        TypeError: Cannot read property 'click' of null\n  (Session info:
        chrome=37.0.2062.94)\n  (Driver info: chromedriver=2.10.267517,
        platform=Linux 3.5.0-45-generic x86)</p>
  </blockquote>
  
  <p>Anybody knows why this is happening? Its kind of hard reloading everytime just for it to work correctly.</p>
