Rails Carrierwave & s3: wrong number of arguments (2 for 1) - ruby-on-rails

Question

new to CarrierWave, already loving it, so much better than Paperclip. Rails 3.2.1
I got it successfully working with local storage, but now trying to move to S3 and get a strange error on _url method (or the database column)
ArgumentError: wrong number of arguments (2 for 1)
Here's my uploader:
class PictureUploader < CarrierWave::Uploader::Base
include CarrierWave::RMagick
storage :fog
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
process :resize_to_limit => [200, 200]
def extension_white_list
%w(jpg jpeg gif png)
end
end
Everything works fine with local storage, and with S3 / fog the file gets uploaded and resized to S3, I can see it in the bucket; there just seems to be a problem with the field / field_url method which gives the error (2 for 1)
I've set non-public s3:
CarrierWave.configure do |config|
config.fog_credentials = {
:provider => 'AWS', # required
:aws_access_key_id => 'xxx', # required
:aws_secret_access_key => 'yyy', # required
:region => 'eu-west-1' # optional, defaults to 'us-east-1'
}
config.fog_directory = 'attachprod' # required
config.fog_public = false # optional, defaults to true
end
This is in my view:
<%= image_tag current_user.profile.picture_url %>
