If in a firewatir script you look for a form using xpath, you’ll get the following output:
SystemStackError: stack level too deep

Known bug, apparently:

Get around it by using :id or some other locator. Here’s some code to replicate the above:
require "FireWatir"
include FireWatir
@browser = Firefox.start("http://www.google.com")
@browser.form(:xpath, "//form").exists?
