pymongo bson segfault

      Fedora 17, pymongo 2.1.1

      I just tried loading an invalid BSON document using the bson module from pymongo. I would expect this to throw an exception, not segfault. (I'm aware that validation isn't used, but I think that is a separate issue from segfaulting, which is almost never acceptable).

      >>> b.decode()
      Segmentation fault
