I noticed this too. I was working on improving this message a bit but
got side tracked and since I figured this did not happen often
anymore, this fix got lower priority than others. I'll resume that

There is another thing we could do. One bad HEAD should not abort the
entire operation (at least if it's not the current worktree's HEAD).
We could still give a warning and move on, or don't warn at all and
let "git worktree prune" collect it (which I see from your message
that it also fails to do).

I guess that's two more items on my todo list :) Sorry for all the
trouble because of this bug of mine.
