That's the right behavior when newvers is nil, isn't it?

I think it was written assuming (incorrectly) that "newvers == nil".
Is the bug fixed if you add (null newvers) to the conjunction?

PS: I see you've already removed this code, but I remember we added
specifically upon request from some users, so it would be better to fix
it than to remove it.
