Thanks for the patch, but it doesn't seem to work, X memory still grows.
You can easily test it with this small script. Replace file.jpg with a
real file, and watch X memory grows with "top", don't let it grow too
much ...

#!/usr/bin/perl
use strict;
use warnings;

use Gtk2 "-init";

my $pb=Gtk2::Gdk::Pixbuf->new_from_file("file.jpg");
Glib::Timeout->add(100,\&do);

Gtk2->main;

sub do
{ my ($pixmap,$mask)=$pb->render_pixmap_and_mask(1);
print STDERR ".";
}
