The above is equivalent to

---
class B < A
    def method1( argument )
       puts argument
       super(argument).method1( argument )
    end
end
---

Just write this as

---
class B < A
    def method1( argument )
       puts argument
       super
    end
end
---

and things will work as you probably intended.
B.t.w this also works if you modify the argument
supplied to super, as in

---
class A
  def mth(s)
    yield s
  end
end

class B < A
  def mth(s)
    super(s+'b')
  end
end

class C < B
  def mth(s)
    super(s+'c')
  end
end

C.new.mth('a') {|x| p x + 'd' } #  => "abcd"
