I am not sure if it is still the process to post patches on the
mailing list, but I hope so. The recent merge request #52
causes crashes because of a missing call to cairo_surface_reference in
cairo_quartz_image_surface_create (since the original surface is
destroyed by the quartz_image_surface, it should be referenced first).
Please find a patch below to fix the problem:
