Need Help

I have this application installed on my computer
apache HTTP Server 2.2
Ruby 1.8.7
Gems
Rails
Mysql 5.1

in appache configuration file i made some change:

unmark AddHandler cgi-script .cgi .rb

Then i go to command prompt with ruby then type this:

rails Testing
C:\Testing\ruby script\generate controller mytest
C:\Testing\ruby script\server

So the server up and running, then i type this on the browser

http://localhost:3000/

The welcome aboard page show up

and when i type this on the browser: http://localhost:3000/mytest

C:/Ruby/lib/ruby/1.8/timeout.rb:58: [BUG] Segmentation fault
ruby 1.8.7 (2010-01-10 patchlevel 249) [i386-mingw32]

This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application's support team for more information.

and in the browser say We're sorry, but something went wrong. We've been
notified about this issue and we'll take a look at it shortly.

Could anybody tell me where i did wrong, its just simple code?
From what i read it suppose to say something like error can't find index
in mytest
because i havent define index in controller mytest

For your information i already change database.yml in config folder

development:
  adapter: mysql
  database: db
  username: root
  password: pass
  host: localhost
test:
  adapter: mysql
  database: db
  username: root
  password: pass
  host: localhost
production:
  adapter: mysql
  database: db
  username: root
  password: pass
  host: localhost

Thank you for any replies, i really appreciate it

by far the easiest way to use rails with apache is to use passenger:
