[DRE-maint] Bug#498558: libgdk-pixbuf2-ruby1.8: scale() of Gdk::Pixbuf leaks memory

[Johan Walles]

Package: libgdk-pixbuf2-ruby1.8
Version: 0.17.0~rc1-4
Severity: important


Run the below program on some image file:

"
#!/usr/bin/ruby

require 'gtk2'

unless ARGV.size == 1
  puts "Syntax: pixbufmemleak.rb <name of an image file>"
  exit 1
end

imagefile = ARGV[0]
puts "Test image: #{imagefile}"

pixbuf = Gdk::Pixbuf.new(imagefile)
while true
  pixbuf = pixbuf.scale(1000, 1000)
end
"

Current behavior: Ruby's memory usage increases by about 200Mb per second.

Expected behavior: Not much, definitely no memory increase.
