MalformedURLException when generating configuration on an app redefining open()

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Write a small application including a redefinition of open()

   def open(url, options)
     AppEngine::URLFetch.fetch(url)
   end

2. Try to start dev_appserver.rb

What is the expected output? What do you see instead?
Instead of a running development server you'll get a MalformedURLException, 
see the full stacktrace in the attached file. 

What version of the product are you using? On what operating system?
0.0.2 on Windows Vista 64Bit

Please provide any additional information below.
I used the redefinition of open() to workaround Google's restrictions using 
an existing library which uses open().

Attention! This does only happen when your configuration is generated. If 
you have an existing configuration you can use the redefinition like 
expected. This required quite some time to find out. I'm pretty sure this 
is because open() is used when generating the configuration. So maybe this 
is a WontFix, but maybe there's a way to run the app inside some sort of 
sandbox. Don't know exactly.

Can you use open-uri instead?

Using open-uri should solve this.
