File with unreadable (?) permissions, mucks up rsync

[reikred at gmail.com]

I have a file in /home/<user>/.emacs.d/auto-save-list which has unreadable (?) permissions,
and also cannot be deleted, at least not by conventional means

-????????? ? ?    ?       ?            ? .saves-2879-homepc.localdomain~

Any thoughts on how to get rid of this file? It is mucking up my rsync jobs, rsync
reports that the file has disappeared and that there is an I/O error.
