Rails - Feb 2006 - ArgumentError (string contains null byte) -- file upload problem

Hi,

Controller code:
    if params[:main_image]
      image = Image.new
      image.blob = params[:main_image].read
      @product.main_image.destroy if @product.main_image
      @product.main_image = image
    end

When I try to display the image using send_data, I get the following error:
ArgumentError (string contains null byte):
    .//vendor/rails/actionpack/lib/action_controller/streaming.rb:55:in
`file?''
    .//vendor/rails/actionpack/lib/action_controller/streaming.rb:55:in
`send_file''
    .//app/controllers/images_controller.rb:5:in `show''


Here''s the image controller:
class ImagesController < ApplicationController
  def show
    image = Image.find params[:id]
    send_file image.blob, :type => ''image/jpeg'',
:disposition => ''inline''
  end
end

Any ideas?
Joe

Gah, I wanted send_data, not send_file.
