Yeah, if it were 18-only we'd need a powwow about whether to break
release freeze. But since it's been there since 17 and nobody
noticed, I'm content to wait till after 18.0 to fix it.

I believe you need to be superuser to reach the bug at all, otherwise
permissions checks should stop you earlier. This makes it less urgent
than it would otherwise be.
