[cairo] Very large number of lines

[Arjen Nienhuis]

  cairo_stroke(cr);
  std::cout << cairo_status(cr) << std::endl;
  cairo_surface_finish(surface);
  std::cout << cairo_status(cr) << std::endl;
  cairo_surface_flush(surface);
  std::cout << cairo_status(cr) << std::endl;
  cairo_surface_destroy(surface);
  std::cout << cairo_status(cr) << std::endl;
  cairo_destroy(cr);
  std::cout << cairo_status(cr) << std::endl;

gives me:

0
0
0
0

0

And there is plenty of memory. I did an strace and i ran it in gdb and there
are no errors. The pdf file is there without /Kids.

1 0 obj
