http://dev.rubyonrails.org/svn/rails/tags/rel_1-2-6/activeresource' doesn't exist

I'm attempting to update my frozen rails version from 1.2.5 to 1.2.6
and I get this error about activeresource not existing in 1.2.6 which
appears to be true. However, I'm just wondering why I get this
message; what is telling "rake rails:freeze:edge" to checkout
activeresource when it's not there to checkout in the first place ?

Here's the output I get when I try to freeze up to 1.2.6. My
application is working fine after the freeze and a restart, however it
would be nice to get rid of this error.

activeresource' doesn't exist

After freezing it the first time, freeze it again. The first time
will update the rails:freeze:edge rake task and the next time will
fetch activeresource.

This doesn't seem to work but thanks for the hint as to where I should
look:

In http://dev.rubyonrails.org/svn/rails/tags/rel_1-2-6/railties/lib/tasks/framework.rake,
the code still seems to want to check out activeresource:

    desc "Lock to latest Edge Rails or a specific revision with
REVISION=X (ex: REVISION=4021) or a tag with TAG=Y (ex:
TAG=rel_1-1-0)"
    task :edge do
      $verbose = false
      `svn --version` rescue nil
      unless !$?.nil? && $?.success?

  < SNIP >

        touch "vendor/rails/REVISION_#{ENV['REVISION']}"
      end

      for framework in %w(railties actionpack activerecord
actionmailer activesupport activeresource)
        system "svn export #{rails_svn}/#{framework} vendor/rails/
#{framework}" + (ENV['REVISION'] ? " -r #{ENV['REVISION']}" : "")
      end
    end
  end

Which explains why running this multiple times is not solving the
problem. Perhaps I am just mis-using rake; I am trying to freeze my
code with 1-2-6 so I just did this:

  % rake rails:freeze:edge TAG=rel_1-2-6
