As you might guess the file mentioned above is a Windows file. I was
getting similar I/O errors using a cp -av command also, although it
wasn't on the same file.
That errors occurred on a Windows file was coincidence, of course. On
which file an error would occur seemed arbitrary.
Anyone see this kind of error before with rsync?
Well, I have seen something similar. However, it was a couple versions
ago and I was trying to transfer to Solaris. There were endianness
problems.

Do you have some cheap router/firewall in between them? One of the
standard problems with torrent files is that occasionally a router will
rewrite a chunk of bytes that it thinks is an IP address but is actually
data. Very annoying.
It seems having a "cheap" router and switch may have been the problem.
The source server was outrunning the destination server (NAS). The
solution seemed to be a switch with flow control (TRENDnet TEG-S80TXE)
between the router and other LAN devices. Neither of my routers (Linksys
RV082 & Netgear FVS318) nor my switches (Linksys EZXS55W) used any kind
of flow control.
The TRENDnet switch also happens to be gigabit, as is the NAS Ethernet
port, and I used a CAT 6 cable, but I have no reason to think the
(potentially) higher speed connection had any effect. No other devices
are gigabit.
The problem with corrupt files are gone, although I still had a few
(eight total, actually) of these errors:
...
cp: setting permissions for
`/eighthome/dallen/forge/dos/ida/ids/win/comctl32.ids': Input/output error
cp: setting permissions for
`/eighthome/dallen/backed-up/games/d2/crashtestdummy.ma0': Input/output
error
...
Doing a diff on those files (src vs. dest.) showed no difference, and
the permissions also copied across alright. Copy speed was constant
throughout the whole copy process, whereas before, the throughput got
consistently slower as the copy progressed. I copied two large
directories, but only experienced the above errors on one of them. These
are the same two directories I had problems with before.
The command used was
cp -av dallen /eighthome/ 2>errorfile.log
while cd'ed to the parent of the source directory copied, with the
command executed from a third box on the LAN via SSH.
