How to do a simple `Date.today` in my Rails console

Question

When I execute the command Date.today in my rails command, I get the following error:

I can't do a simple Date.today in my Rails console

ruby-1.9.2-p180 :026 >   >> require 'date'
 => false 

ruby-1.9.2-p180 :027 >   >> Date.today
ArgumentError: invalid date
    from /Users/besi/.rvm/rubies/ruby-1.9.2-p180/lib/ruby/1.9.1/date.rb:809:in `civil'
    from /Users/besi/.rvm/rubies/ruby-1.9.2-p180/lib/ruby/1.9.1/Date.rb:1810:in `today'

    from -e:1:in `load'
    from -e:1:in `<main>'

In the irb console this works without problems:

ruby-1.9.2-p180 :001 > require 'date'
 => true 
ruby-1.9.2-p180 :002 > Date.today
 => #<Date: 2013-04-15 (4912795/2,0,2299161)>

It looks like there is a problem with the RubyMine Plugin here. When I do the same thing in the console it works. I don't know though why such a simple thing should not work in RubyMine.
