Bug reproduction:
{code:ruby}
require 'rexml/parsers/streamparser'
require 'rexml/parsers/baseparser'
require 'rexml/light/node'
require 'rexml/text'

xml = "<?xml version=\"1.0\" encoding=\"windows-1251\"?> <catalog>  <book id=\"bk101\">  <author>Gambardella, Matthew</author>  <title>XML Developer's Guide</title>  <genre>Computer</genre>  <price>44.95</price>  <publish_date>2000-10-01</publish_date>  <description>An in-depth look at creating applications   with XML.</description>  </book> </catalog>"
parser = REXML::Parsers::BaseParser.new(xml)
{/code}

Calling stack:

lib/ruby/1.9/rexml/parsers/baseparser.rb:127 SourceFactory.create_from(source)
lib/ruby/1.9/rexml/source.rb:17 IOSource.new(StringIO.new(arg))
lib/ruby/1.9/rexml/source.rb:46 self.encoding = check_encoding( @buffer )
lib/ruby/1.9/rexml/source.rb:55 return unless super
lib/ruby/1.9/rexml/encoding.rb:9 encoding = find_encoding(encoding)
lib/ruby/1.9/rexml/encoding.rb:55 ::Encoding::Converter.search_convpath(name, 'UTF-8')

{/code}

Bugfix with monkey patching (code was taken from Rubinius)

Unable to find source-code formatter for language: ruby. Available languages are: _javascript_, sql, xhtml, actionscript, none, html, xml, java
Encoding::Converter.instance_eval do
    def search_convpath(from, to, options={})
      new(from, to, options).convpath
    end
