Hmm, this patch isn't as clear to me. Even if this can return NULL now,
it'll soon crash at some later point, no?
IMHO such patch is more suitable to be included in the same patch where
such new tests will be introduced, then we're addressing some real test
code changes that will work, rather than worrying on what will happen in
the future (and as I mentioned, i don't think it fully resolved that either..)
Thanks,
