help testing Rails patches / tickets

I'm new to this and trying to test this patch:
https://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/3645

Steps:
git clone git://github.com/rails/rails.git
git checkout v3.0.0.beta1 (I assume this is what the patch works on
judging by the date?)
git am < ~/labels-with-blocks.diff

Doing this I get lots of errors like "error: patch failed: actionpack/
lib/action_view/helpers/form_helper.rb:505"

Am I doing something wrong?

thanks!!

Can anyone help me out with some tips?

Have you tried the patch against 2.3-stable ?

Or another possibility is that the source has changed enough that the
patch just doesn't apply cleanly anymore.
