Rake resque: failing with simple example

I wanted to start with resque. So I created three files, one to create a dummy job and two others to process it:

    --- image_transformer.rb ---
    # coding: UTF-8
    class ImageTransformer
      @queue = 'image_transform_queue'

      def self.perform (asset_id)
        puts "perform"
        puts asset_id
      end
    end


    --- create_job.rb ---
    # coding: UTF-8
    require 'resque'
    require_relative 'image_transformer'

    Resque.enqueue (ImageTransformer, 'test')


    --- Rakefile ---
    # coding: UTF-8
    require_relative 'image_transformer'
    require 'resque / tasks'

Then I first run $ ruby ​​create_job.rb with no problem. I see work in the resque queue.

Now I want to start a worker, but that fails:

    $ QUEUE = * VVERBOSE = 1 VERBOSE = 1 rake resque: work --trace
    ** Invoke resque: work (first_time)
    ** Invoke resque: preload (first_time)
    ** Invoke resque: setup (first_time)
    ** Execute resque: setup
    ** Execute resque: preload
    ** Invoke resque: setup
    ** Execute resque: work
    *** Starting worker anpr-THINK: 15292: *

    Tasks: TOP => resque: work

Does anyone know what's going on? It looks like an encoding problem, but where?

I am using Windows 7 (if needed).

EDIT: I have pasted the debug output into the "#encode" method: {: queue => "image_transform_queue" ,: run_at => "2012/03/28 13:25:53 Mitteleurop \ xE4i sche Sommerzeit",: payload => {" class "=>" ImageTransformer "," args "=> [" test "]}}

Apparently the problem is that the ": run_at" value contains a German umlaut (that's my locale).

To get this from an unanswered list:

I pasted the debug output into the '#encode' method:



{
    :queue=>"image_transform_queue",
    :run_at=>"2012/03/28 13:25:53 Mitteleurop\xE4i sche Sommerzeit",
    :payload=>{"class"=>"ImageTransformer", "args"=>["test"]}
}

Apparently the problem is that the value :run_at

contains a German umlaut (that's my locale).
