Rsync iconv (Cygwin) (file has vanished)

[Brendan Grieve]

I have another question. I'm not sure if this is the correct post for 
cygwin rsync related questions.

I've compiled rsync 3.0.0pre8 under cygwin. Works splendidly and 
compiles cleanly. I made sure to have libiconv installed and it supports 
the --iconv command (at least it accepts it).

I've been using rsync to test a backup of some files from a windows box 
to a linux box. I use the following command under windows: -
rsync.exe  -v -rlt -z --delete -y --delete-excluded 
--partial-dir=/.rsync-partial --iconv=utf-8,utf-8 
"/cygdrive/D/Data_Tier1/" "username at server::virtualdir/Data_Tier1/"

I get the following error on files that have russian cryllic letters: -
---
file has vanished: "/cygdrive/D/Data_Tier1/Home/xxx/??????? ???????? ????"
(thousands more entries similar)
---

Am I doing something wrong? I've also using: -
  --iconv=.

The user I run as definitely had permissions on those files.
