Subject: Exception instances...

I don't understand where the following warning is coming from:

> ruby -w test_exeptions.rb
Start
test_exceptions.rb:14: warning: instance variable mesg not initialized
TestingError
Just testing...
Finish.


### Begin: test_exceptions.rb
class TestingError < StandardError
  attr_reader :uga
  def initialize (booga)
    @uga = booga
  end
end # class TestingError

begin
  puts 'Start'
  raise TestingError.new('booga?'), 'Just testing...'
rescue TestingError => reason
  puts reason      # This is line 14
  puts reason.uga
ensure
  puts 'Finish.'
end
### End: test_exceptions.rb


I'm pulling this example from the Pick-axe and ... I'm not sure what
the problem is.  How can I get TestingError#uga?  Somehow I want to be
able to print out 'booga?' but I don't know where that info is getting
stashed.
