Subject: How to debug 'ri' ?

I'm seeing this all of a sudden:
C:\>ri Dir
c:/ruby/lib/ruby/1.8/rdoc/ri/ri_descriptions.rb:99:in `concat': can't
convert nil into Array (TypeError)
        from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_descriptions.rb:99:in `merge_in'
        from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_reader.rb:56:in `get_class'
        from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_reader.rb:52:in `get_class'
        from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_driver.rb:70:in
`report_class_stuff'
        from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_driver.rb:106:in `get_info_for'
        from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_driver.rb:135:in `process_args'
        from c:/ruby/lib/ruby/1.8/rdoc/ri/ri_driver.rb:134:in `process_args'
        from c:/ruby/bin/ri.bat:55

:(, it crashes fxri also if I type 'Dir' into the search box.

Kind thanks in advance for any insight,
