To be perfectly clear, do you mean you have tried Vitorio Machado's
patch?

If not, that may be worth a try.

This may just be an oddity with the network filesystem, but that doesn't
explain why it would happen only with a --delete option, which shouldn't
significantly change rsync's access pattern to the network-mounted
source.  If you ktrace the relevant rsync process with and without
--delete, that might provide some clues about what triggers the error.

Since the error only happens with --delete and appears to involve
xattrs, you may be able to work around it by using two passes of rsync,
the first with -X but not --delete and the second with --delete but not
-X.
