Thanks for checking. Unfortunately, I haven't been able to either. The
errors do not re-appear if I manually put "var/lib/rpcbind" back in the
destination directory and run the script again.
(By the way, in case it makes any difference: both sides were upgraded
from 2.6.9 to 3.0.2, so it's using the new "delete-during" default.)

I'm not sure if you caught this, but the "File exists" error was
actually returned on the directory two levels up from the file: "var".

Shouldn't be. On the receiving side, rsync is the only program that ever
touches the files. (And there's never more than one rsync instance
running at a time; the script is executed once per day from cron.)
I suspect the ENOENT result in keep_backup() must be correct because the
verbose output from the rsync run appears to indicate that
"rpcbind.file" -- the file that generated these errors -- was deleted
from the directory *first*:
cannot delete non-empty directory: var/lib/rpcbind
If I understand correctly, at that point, "var/lib/rpcbind" could not
already exist in the backup directory. (There are no references to
"var/lib/rpcbind" before that in the output.)
