Summary: Date.parse raises NoMethodError

Initial Comment:
In the version 1.8.4 

Date.parse('-1') 

used to raise 'ArgumentError: invalid date' error. Now it raises NoMethodError:

irb(main):002:0> Date.parse '-1'
NoMethodError: undefined method `[]' for nil:NilClass
        from /usr/local/lib/ruby/1.8/date.rb:800:in `complete_hash'
        from /usr/local/lib/ruby/1.8/date.rb:875:in `new_with_hash'
        from /usr/local/lib/ruby/1.8/date.rb:922:in `parse'
        from (irb):2
        from /usr/local/lib/ruby/1.8/rational.rb:174

The patch below fixes it:
