selenium browser error with Chrome - selenium

Question

I'm getting the following error from selenium:
File "clint-selenium.py", line 58, in <module>
browser = Chrome()
File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/chrome/webdriver.py", line 69, in __init__
desired_capabilities=desired_capabilities)
File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 92, in __init__
self.start_session(desired_capabilities, browser_profile)
File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 179, in start_session
response = self.execute(Command.NEW_SESSION, capabilities)
File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 234, in execute
response = self.command_executor.execute(driver_command, params)
File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/remote_connection.py", line 407, in execute
return self._request(command_info[0], url, body=data)
File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/remote_connection.py", line 439, in _request
resp = self._conn.getresponse()
File "/usr/lib/python2.7/httplib.py", line 1136, in getresponse
response.begin()
File "/usr/lib/python2.7/httplib.py", line 453, in begin
version, status, reason = self._read_status()
File "/usr/lib/python2.7/httplib.py", line 417, in _read_status
raise BadStatusLine(line)
httplib.BadStatusLine: ''
I am calling it with code:
from contextlib import closing
from selenium.webdriver import Chrome # pip install selenium
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
browser = Chrome()
browser.get('http://www.google.com')
time.sleep(1)
print browser.title
browser.quit()
I have evidently done something to my laptop because this used to work. Any thoughts
EDIT
I've tried updating chromedriver but I'm now getting
Traceback (most recent call last):

This seems to indicate I'm still not using the latest version. I've followed a couple of guides about installation and I'm getting the same result. Any thoughts

Answer 1

Chromedriver was apparently updated on 2016-10-22, after which I also encountered this problem. Updating to the new version of Chromedriver (2.25) fixed it for me.
