Comment(by jballanc@…):

 This is, oddly enough, the correct behavior. In the 1.9 series, Ruby
 started always reporting arity -1 for #new. If you want the actual arity
 of the initialize method, you have to be explicit:

  {{{

 irb(main):001:0> class Test
 irb(main):002:1>   def initialize(arg)
 irb(main):003:1>   end
 irb(main):004:0> end
 => nil
 irb(main):005:0> Test.method(:new).arity
 => -1
 irb(main):006:0> Test.instance_method(:initialize).arity
 => 1
 }}}
