I18n::MissingInterpolationArgument with I18n.l

I get this error I18n::MissingInterpolationArgument when running this code

<%= l Date.today, :format => :short %>

It has worked before, but now, at Ubuntu, with Rails 2.3.5 and Ruby 1.8.7 (2010-06-23 patchlevel 299) [i686-linux] it doesn't work开发者_开发技巧 anymore ...

Anyone to help?

Okey, got a quickfix for myself. Not the way I would have it, but it works

Added this to the en.yml file

  date:                   
    formats:              
      default: "%d.%m.%Y" 
      short: "%b %e"      
      long: "%e. %B %Y"
