Bug description:
  I was trying my program with python. In this program I use GTK3
  (gi.repository.Gtk), and I have a Glade interface, with a spinner. I
  looked for  a method to start the spinner, and I found
  Gtk.Spinner().start(). I added the line in the program, and the
  problem occurred. This is the stdout:

  python: /build/buildd/cairo-1.10.2/src/cairo-surface.c:614: cairo_surface_reference: asserzione "((*&(&surface->ref_count)->ref_count) > 0)" non riuscita.
  Annullato (core dump creato)

  Translation to English:
  python: /build/buildd/cairo-1.10.2/src/cairo-surface.c:614: cairo_surface_reference: assertion "((*&(&surface->ref_count)->ref_count) > 0)" failed.
  Canceled (core dump created).
