No, it's an error. I guess Anders meant "crash *of* auto-revert"

The latter one. Anders has explained me that there is a design goal of
auto-revert, to leave the buffer unchanged in such cases. A user could
have deleted the file by accident, and she could use the unchanged
buffer for restoring the file.
I'll try to prepare a patch. If it is as simple as I do expect, it could
go to the emacs-25 branch.
Best regards, Michael.
