problem on win7

[ArtemHarchishin]

When I do rake task , I have a warning like this:
** Execute translation:yml:to_swf
C:/Ruby192/lib/ruby/gems/1.9.1/gems/rake-0.9.2/lib/rake/rake_module.rb:26: warni
ng: redundant nested repeat operator
rake aborted!
undefined method `cache' for Gem:Module

(See full trace by running task with --trace)
** Execute translation:yml:to_as_and_swf

I added trace in /rake_module.rb:26 , and saw it :
