watir-webdriver works with Firefox but not with Chrome :Failed to initialize session (Selenium::WebDriver::Error::WebDriverError)

[emclaus]

I'm trying to use Watir and Chrome (Chromium version 10.0.648.205 on
Ubuntu) together. I think I have watir-webdriver installed correctly
because I can get a firefox window to open without any problems.
Could it have something to do with using Chromium instead of Chrome?
In the changes file in the selenium-webdriver folder it states "Added
'chromium' as a possible name for the Chrome binary (#769)"

I have Ruby 1.8.7 and my gem list is:

builder-3.0.0
childprocess-0.1.8
commonwatir-1.8.1
ffi-1.0.7
firewatir-1.8.1
hoe-2.9.4
json_pure-1.5.1
rake-0.8.7
rubyzip-0.9.4
s4t-utils-1.0.4
selenium-webdriver-0.2.0
user-choices-1.1.6.1
watir-webdriver-0.2.3
xml-simple-1.0.15

My program is:
require 'rubygems'
require 'watir-webdriver'
browser=Watir::Browser.new(:chrome)
#browser=Watir::Browser.new(:firefox) ##### This works fine!

My error output is:

As mentioned on the server download page, you need a newer version of
Chrome, minimum version 12.0.727.0.
