Subject: ruby-debug does not hit breakpoints at class-methods

ruby-1.8.6-p369
ruby-debug-0.10.3

How to set breakpoints at class-methods without editing source of
library files? And without line numbers?

$ cat test.rb
require 'ruby-debug'

class Aaa
  def self.cl_aaa
    puts 'A A A'
  end
  def initialize
    @aaa = 'a a a'
  end
  def aaa
    puts @aaa
  end
end

debugger

a = Aaa.new
Aaa.cl_aaa
a.aaa

$ ruby test.rb
< or >
$ rdebug test.rb
test.rb:<lineno of debugger>
a = Aaa.new
(rdb:1) b Aaa:cl_aaa
Breakpoint 1 at Aaa::cl_aaa
(rdb:1) b Aaa:aaa
Breakpoint 2 at Aaa::aaa

(rdb:1) i b
Num Enb What
  1 y   at Aaa:cl_aaa
  2 y   at Aaa:aaa

(rdb:1) cont
A A A
Breakpoint 2 at Aaa:aaa
test.rb:<lineno of 'def aaa'>
def aaa

(rdb:1) i b
Num Enb What
  1 y   at Aaa:cl_aaa
  2 y   at Aaa:aaa
  breakpoint already hit 1 time
(rdb:1) cont
a a a
$

The same result if it was used '#' or '.' instead of ':', i.e.
'Class#method' or 'Class.method'.
