Rails 3 :getc problem, temporary fix

# Put this file eg. xml_parser.rb into your config/initializers directory, reboot your application

ActiveSupport::XmlMini.backend = "Nokogiri"

module ActiveSupport
  module XmlMini_Nokogiri
    
    def parse(data)
      if !data.respond_to?(:read)
        data = StringIO.new(data || '')
      end
      
      responds_to_getc = data.respond_to?(:getc)
        
      if responds_to_getc
        char = data.getc
        data.ungetc(char)
      end  
      
      if char.nil? && responds_to_getc
        {}
      else
        doc = Nokogiri::XML(data)
        raise doc.errors.first if doc.errors.length > 0
        doc.to_hash
      end
    end
    
  end
end

For the above example, I've used the nokogiri gem for the backend parser, so you may need to add it to your Gemfile
