Hello, I haven't looked at this but judging from the general shape of function and error message, it seems clearly a bug that needs to be fixed somehow. I'll try to make time to look at it sometime soon, but I have other bugs to investigate and fix, so it may be some time. I fear your proposal of ignoring the object may be the best we can do, but I don't like it much. -- Álvaro Herrera 39°49'30"S 73°17'W "La verdad no siempre es bonita, pero el hambre de ella sí"
