rsync is not copying upper case files

Hi, I have eliminated OSX from the problem space since the same error
occures from linux to linux. The only difference is that the linux rsync
gives me the (probably unrelated) error message:

failed to set permissions on test-sync : Operation not permitted
failed to set permissions on test-sync : Operation not permitted
rsync error: partial transfer (code 23) at main.c(578)

This error message does not occur when transfering to a linux partition,
but only when transfering to a fat32 partition.

But I could encircle the problem from another side:
The problem only occures if I use the --delete-after option in the
following command:
 rsync -aL --delete --delete-after -e ssh test-sync  user at machine:/mnt/hda8/backup

If I don't use the --delete-after option, then the files are copied
properly from linux to linux partition and to the fat32 partition.
If I use the --delete-after, then "UPPER CASE file", when transfered
to the fat32 partition are not copied and even deleted, if they already
exist.

So, I think it is due to the fact that an all UPPER CASE file name is
converted to an all lower case file name on the fat32 partition,
which then, since the original file name was different, is instantly
deleted when  --delete-after was chosen.
So my guess is that this could cause the problem.
