Strange behaviour with Prawn

prawn-oddness.rb

require 'rubygems'
require 'prawn'
pdf = Prawn::Document.new(:page_size => "A4", :page_layout => :landscape)
pdf.bounding_box [0, pdf.bounds.height - 40,], :width => 740 do

  # No Entries
  #
  pdf.table([["Total Value of Spend", "Total Transactions", "Average Transaction Value"], ["4558.5100", "30", "151.95033333"]], :header => true) do
    row(0).style(:style => :bold, :background_color => 'cccccc')
  end

  pdf.move_down(10)

  # Works
  #
  pdf.table([["Total Value of Spend", "Total Transactions", "Average Transaction Value"], ["4558.5100", "30", "151.95033333"]])

  pdf.move_down(10)

  # Works.
  #
  pdf.table([["Total Value of Spend", "Total Transactions", "Average Transaction Value"], ["4558.5100", "30", "151.95033333"]], :header => true, :cell_style => { :borders => [] })

  pdf.move_down(10)

  # Suddenly Works
  #
  pdf.table([["Total Value of Spend", "Total Transactions", "Average Transaction Value"], ["4558.5100", "30", "151.95033333"]], :header => true) do
    row(0).style(:style => :bold, :background_color => 'cccccc')
  end

end
pdf.render_file('test.pdf')

Trying to upgrade some Prawn 0.8.4 to 0.10.2 so I can use more of the nifty table / layout stuff in a project, when I ran into this simplified problem. The generated table contains absolutely no data.

Ruby 1.8.7 and prawn 0.10.2 gem.

Adding more examples with the same data, it eventually starts working.

Changing the order of things around, it seems as if the first table is always empty.

Removing the Bounding box solves the problem
