possible memory leak in cairo?

Magick,
I am no familiar with Cairo, my vld tool report there is memory leak in imagemagick-6.8.8\cairo\src\cairo-image-surface.c (181): _cairo_image_surface_create_for_pixman_image.
I checked that chunk source code.
it looks like the surface object been created but only return one of its member, I don't know if the surface object has been left behind or it will be collected by some other process. Since IM use Glib, my memory leak detector tool doesn't work anymore. I have to ask you to clarify this one.
Sorry for the million questions I posted in last couple days. This is a major update, my test set files generated lots of problem.

if (unlikely (surface == NULL))

_cairo_image_surface_init (surface, pixman_image, pixman_format);
return &surface->base;
