No, you're not.  That appears to be a resource leak because of a  
reference leak in the bindings.  gdk_pixbuf_render_pixmap_and_mask()  
and gdk_pixbuf_render_pixmap_and_mask_for_colormap() return brand-new  
GdkDrawables, but the bindings do not take ownership of the new  
objects.  The GObjects leak, so the underlying X resources leak.

Please try the attached patch.

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 ...

use strict;
use warnings;

use Gtk2 "-init";

my $pb=Gtk2::Gdk::Pixbuf->new_from_file("file.jpg");


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