I have found a work around to the original stack trace. I think
it the issue has something to do with the fonts on my machine
but I expect it should handle missing fonts more gracefully.
I have installed more fonts but it made no difference. Anyway,
the following change fixes the bug:

Change lines 173-177 of rubyide_tools_fox_ri/fxri/fxri.rb
to this
                font = load_font($cfg.ri_font)
                @gui.text.font = font if font
                font.create if font
                @gui.text_width = 10
                @gui.text_width = font.fontWidth if font

Similar error in Ruby 0.9.5 on Windows XP Pro.  If I just type
"Y" in the Ruby Doc search / text windows, Ruby closes
with no error message, but I can get an error trace with the
following sequence:

Open FreeRIDE ==> Ruby Doc in detached / undocked window ==>
scroll until YAML visible ==> click YAML (the class)

NoMethodError: undefined method `join' for
"YAML":String
