Ok, after some work we can recreate this with the following:

#########################################
require 'tk'

root = TkRoot.new() do
   title 'Some title'
end

bad = TkButton.new(root) do
   text 'bad'
   command do
     puts 'bad'
     win = TkToplevel.new(root) do
       title  "Bad window"
     end

     names = ['a', 'b']
     operator_var = TkVariable.new()
     operator = TkOptionMenubutton.new(win, operator_var, *names)
     operator.pack
   end
end
bad.pack

Tk.mainloop()
##########################################


This will pop up a frame with a single button called bad.  You can click 
the bad button and the bgerror problem occurs for us.

The stack trace with this smaller test case is:
