Thanks for reporting this bug, it looks like we never actually destroy the
stream along the normal path either.

type1: Destroy the output stream.
mpsuzuki spotted that the output stream for the subset was not being
destroyed on the error path - on closer inspection, it wasn't destroyed
along the normal path either and may never have been correctly
initialised to NULL on an earlier error.
