strange errors in dev.log and webserver log

Hi guys,

I have encountered a strange error in one of my applications.

The details are the following:

The application is a very simple one, I have one model, Cards, it has
some pretty basic stuff, some after_save methods for saving uploaded
files to their places.

I have an UI where I can manage the Card records, with the default
methods, including 'edit'

cards_controller.rb:

# def edit
# logger.info "Loading Card with ID: #{params[:id]}"
# @card = Card.find( params[:id] )
# end

Now each time I use the /cards/edit/3 (or any other valid id), I got
my card object properly loaded up onto the admin ui.

However - and here comes the strangeness - I see the following errors
in my dev and web logs:

development.log:
