Paperclip + ImageMagick on Windows 7: Image display fails when I add styles to attached_file in model

Question

I'm working with Ruby on rails 2.3.8, NetBeans IDE.

I've installed paperclip and I could show/save images successfully. Now, I've installed ImageMagick-6.6.2-4-Q16(for windows 7, 64bits).

Until that moment, my model looked like this(and worked fine):

has_attached_file :photo

Now, after installing ImageMagick, when I add the :style line it fails:

has_attached_file :photo,
    :styles => {:thumb => "100x100#",   :small => "150x150>",   :large => "400x400>" }

and it throws the following error message when I try to upload an image:

 TypeError in ProfilesController#update

backtrace must be Array of String

The only thing I'm doing in the update action of that controller is the following:

  @profile.update_attributes(params[:profile])
  @profile.update_attribute(:photo, params[:profile][:photo])

I've also installed miniMagick gem(because I read somewhere I had to do it).

What am I missing?

Try to download the paperclip version 2.3.1.1, higher versions failed to me.
