FYI, the same thing happens with rspec 2.0.0.beta.20 as well:
1) Service should raise an ArgumentError if currency_amount is nil
Failure/Error: lambda
{ @service.currency_to_dollars(nil) }.should
raise_error(ArgumentError)
expected ArgumentError, got #<NoMethodError: undefined method
`ArgumentError' for #<Service:0x000001029665d8>>
# ./test/spec/service_spec.rb:92:in `block (2 levels) in <top
(required)>'
