Rails 3.2.1 + haml "Missing template" problem

Hello, could you help me.

I create new Rails 3.2.1 project. Put gem haml. Make controller Home/
Index.
Every thing work fine.

After that I rename /app/views/home/index.html.erb to /app/views/home/
index.html.haml

And I got error

Template is missing
Missing template home/index, application/index with
{:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :coffee, :haml]}.
Searched in: * "/vagrant/testprj/app/views"

I development.log more details.

Started GET "/" for 10.0.2.2 at 2012-03-01 14:44:45 +0000
Processing by HomeController#index as HTML
Completed 500 Internal Server Error in 3ms
