send_keys() giving error in python 3 selenium code with firefox - python-3.x

Question

My code is:
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import Select
from selenium.common.exceptions import NoSuchElementException
baseurl = "https://www.google.ca/?gfe_rd=cr&ei=J5ooWerXOsf_8AebtKKICw&gws_rd=ssl"
search = "panda"
xpaths = { 'searchbox' : ".//*[#id='lst-ib']",
'submit' : ".//*[#id='tsf']/div[2]/div[3]/center/input[1]",
'img' : ".//*[#id='gbw']/div/div/div[1]/div[2]/a"
}
driver = webdriver.Firefox()
driver.get(baseurl)
driver.find_element_by_xpath(xpaths['searchbox']).clear()
driver.find_element_by_xpath(xpaths['searchbox']).send_keys(search)
driver.find_element_by_xpath(xpaths['submit']).click()
#driver.find_element_by_xpath(xpaths['img']).click()
Firefox opens, but nothing at all happens, and written in the terminal is the following:
Traceback (most recent call last):
File "sg1.py", line 21, in <module>
driver.find_element_by_xpath(xpaths['searchbox']).send_keys(search)
File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/remote/webelement.py", line 347, in send_keys
self._execute(Command.SEND_KEYS_TO_ELEMENT, {'value': keys_to_typing(value)})
File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/remote/webelement.py", line 494, in _execute
return self._parent.execute(command, params)
File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/remote/webdriver.py", line 236, in execute
self.error_handler.check_response(response)
File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/remote/errorhandler.py", line 192, in check_response
raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: Expected [object Undefined] undefined to be a string
Things to note:
Firefox is up to date.
When Firefox opens it opens a plain version and not the version that usually opens with add-ons such as adblocker, firebug, etc.
When i ran just the click on 'img' bit that is commented out it did what it was supposed too.

This issue is common with geckodriver v.015; In order to resolve this update your geckodriver version to 0.16 also selenium to 3.4.0.
