Andreas, please open a bugzilla report on this problem
(https://bugzilla.filesystems.org/).

When you say "Samba" do you mean you're using smbd on the Linux box, or do
you use something else?

What happens if you try to rename the file using /bin/mv on the unix machine
directly: does that work?

Thanks,
Erez.
