[DRE-maint] Bug#512033: libgruff-ruby: Repeats last color from defined set, resulting in the wrong output image

Package: libgruff-ruby
Version: 0.3.4-1
Severity: normal

Gruff repeats the last color in its 'colors' hash when generating a
graph - So, with the default color set, whenever it is requested to
graph over 7 rows, a graph with two adjacent equal colors will be
generated - See the attached 'gruff_colors.png' file, which is the
output of this:

    require 'gruff'

    g = Gruff::Pie.new
    g.title = 'Gruff colors test'
    10.times { |row| g.data(row, 1) }


Adding an extra color does not help the problem - The output from
adding "g.add_color '#777777'" just after the Gruff initialization
results in the attached gruff_added_color.png.
