How do I get the text contents of a textarea with webdriver?

I'm trying to get the contents of a textarea in an HTML form using webdriver in Python.

I'm getting the text, but newlines are missing. The selenium docs are pretty much useless; they say:

class selenium.webdriver.remote.webelement.WebElement(parent, id_)

[...]

text: Gets the text of the element.

I'm currently doing the following:

from selenium import webdriver

# open the browser and web site
b = webdriver.Firefox()
b.get('http://www.example.com')

# get the textarea element
textbox = b.find_element_by_name('textbox')

# print the contents of the textarea
print(repr(textbox.text))

This prints the representation of a Python unicode string of the textarea's contents, except all the newlines have been replaced by spaces. Doh!

Not sure if I'm facing a text encoding issue, selenium/webdriver bug (couldn't find it in the tracker), or user error.

Is there a different way to do this?

EDIT: I just gave Chrome a try... works fine. I reported a bug to selenium's issue tracker. Sam's workaround (the accepted answer below) works in Firefox with one caveat: symbols are converted to HTML entity codes in the returned string. This is no big deal.
