Here is the Python/GTK way to do this, for what it is worth:
from sugar.datastore import datastore
#my_dsobject is of type datastore.DSObject
#object_id is a datastore object
my_dsobject = datastore.get(object_id)
pixbufloader = gtk.gdk.pixbuf_loader_new_with_mime_type('image/png')
#Access the 'preview' property
#Note that the preview image is 300x225
pixbuf = pixbufloader.get_pixbuf()
