Hi,

I'm running through the Ruby on Rails tutorial at http://guides.rubyonrails.org/getting_started.html (adjusting where appropriate for Google's App Engine). All is well up till section 6.3: when I try to click "New Post", I get the following error:

Internal Server Error (500)  
Request Method: GET  
Request URL: http://localhost:8080/500.html  
access denied (java.io.FilePermission /dev/urandom read)

It works fine when I upload the application to Google's App Engine; it's just on my development machine (OS X 10.6) that it doesn't work.

Thanks in advance.
