Campfire's SSL cert doesn't verify with Ruby 1.9.3 p194

gistfile1.rb

# This works for me in 1.9.3-p125 but not in p194.
# Can anyone explain why?

        require 'net/http'
        http = Net::HTTP.new("theclymb1.campfirenow.com", 443)
        http.use_ssl = true
        http.verify_mode = OpenSSL::SSL::VERIFY_PEER
        request = Net::HTTP::Get.new("/login")
        response = http.request(request)
        raise response.inspect if response.code != '200'

Here is what works for me witih macports and rbenv: https://gist.github.com/2315629
