Subject: ri IO -> RuntimeError

Hi all,

I just noticed that ri fires a RuntimeError when called with
IO

 > ri IO

-------------------------------------------------------------- Class: IO
      Class +IO+ is the basis for all input and output in Ruby. An I/O
      stream may be _duplexed_ (that is, bidirectional), and so may use
      more than one native operating system stream.

      Many of the examples in this section use class +File+, the only
      standard subclass of +IO+. The two classes are closely associated.

      As used in this section, _portname_ may take any of the following
      forms.

c:/ruby/lib/ruby/1.8/rdoc/ri/ri_formatter.rb:152:in `display_list': 
unknown list type (RuntimeError)
	from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_formatter.rb:175:in 
`display_flow_item'
	from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_formatter.rb:225:in `display_flow'
	from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_formatter.rb:224:in `each'
	from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_formatter.rb:224:in `display_flow'
	from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_display.rb:268:in `display_flow'
	from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_display.rb:89:in `display_class_info'
	from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_display.rb:77:in `page'
	from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_display.rb:139:in `display_class_info'
	from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_driver.rb:58:in `report_class_stuff'
	from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_driver.rb:93:in `get_info_for'
	from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_driver.rb:122:in `process_args'
	from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_driver.rb:121:in `each'
	from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_driver.rb:121:in `process_args'
	from c:/ruby/bin/ri:21


This happens on Win98 as well as XP running the 1-click-installer 
version 1.8.1-13.

Has anybody else experienced this behaviour?


Happy rubying

Stephan
