Here's a sample script, which is basically the condensed version of what 
RSSScraper does
---------------------------------
#!/usr/local/bin/ruby
require 'webrick'
require 'open-uri'
include WEBrick

class SegfaultServlet < HTTPServlet::AbstractServlet
  def do_GET(req, res)
    url = req.path.to_s[/.*?\/(.+)/, 1]
    res['Content-Type'] = "text/html"
    res['Url-You-Sent'] = "#{url}"
    STDERR.puts "http://#{url}"
    res.body = open("http://#{url}").read
  end
end
s= HTTPServer.new(:Port => 5363)
s.mount("/", SegfaultServlet)
trap("INT"){ s.shutdown }
s.start
-------------------------------

Run it and use it using some wgets

wget 'http://localhost:5363/slashdot.org' & ; \
  sleep 1 ; \
  wget 'http://localhost:5363/slashdot.org' & ; \
  sleep 1 ; \
  wget 'http://localhost:5363/www.lambda-the-ultimate.org' & ; \
  sleep 1 ; \
  wget 'http://localhost:5363/www.ruby-lang.org'

and sure enough it segfaults, here's another backtrace
