Well, the message itself indicated that it was the new one...

Yes, we could easily do that if we want to.

But - this is not the error you get when you try to set it. It's the
error you get when you try to *use* it. And really, it's a "should
never happen" error. (The reason it happens this time is due to another
bug). So I don't think doing so would actually help your case - it's
already covered elsewhere in the code where we'll rollback the setting
when you try to change it instead of PANICing.
