LibXML::XML::Document.validate(LibXML::XML::Schema) fails with Segmataion fault

[svenk]

Architecture: x86_64
Description: Ubuntu 9.04
Release: 9.04
libxml-ruby1.8: 0.9.4-1

When i call `ruby information_controller_test`, the following code throws an Segmetation fault, but
the same xml / xsd files works with `xmllint --schema version.xsd version.xml` without any problem.

# Start of Code ####

require File.dirname(__FILE__) + '/../test_helper'
require 'libxml'

class MylynConnector::InformationControllerTest < ActionController::TestCase
  def setup
    @controller = MylynConnector::InformationController.new
    @request = ActionController::TestRequest.new
    @response = ActionController::TestResponse.new
  end

  def test_version
    get :version
      .
      .
    xmldoc = LibXML::XML::Document.string @response.body
    schema = read_schema 'version'
    valid = xmldoc.validate schema # produces the segmentation fault
  end

  protected
  def read_schema name
    schemapath = File.dirname(__FILE__) + '/../schema/' + name + '.xsd';
    schemadoc = LibXML::XML::Document.file schemapath
    LibXML::XML::Schema.document schemadoc
  end
end

# End of Code ####

The same xml / xsd files works with `xmllint --schema version.xsd version.xml` without any problem.

Shame on me, i have mistaken the methods.
I have to call validate_schema
