Steps to reproduce:

Create a simple HTML page with a textarea:

<html>
<textarea id="foo"></textarea>
</html>

Launch Firefox with Marionette enabled:

/Applications/Firefox.app/Contents/MacOS/firefox -marionette

Run the Marionette Python client (pip install marionette_driver) with this script:

from marionette_driver.marionette import Marionette
from marionette_driver import By

client = Marionette('localhost', port=2828)
client.start_session()
client.navigate("<the page above>")
element = client.find_element(By.ID, 'foo')
element.send_keys('bar')


Actual results:

Marionette throws an InvalidArgumentException: Expected [object Undefined] undefined to be a string.

Full stack trace:
