rsync --delete problems

[Torben Schou Jensen]

For some time I have been using rsync to backup data between different
machines and my NAS drive.

But within the last 2 days I have found out that rsync is not removing old
files from destination - directories renamed or removed from source.

In this example I want to sync files on my Debian Linux server to a NAS
drive. NAS drive is mounted using smbmount.

Using "-avhzn" dry-run it indicate f3 and file3 to be removed.

==> Method SMBFS mount
==> smbmount <diskstation> /mnt/NAS.20071201.204045 -o
username=root,password=xxx
==> rsync -avhzn --delete --progress /mnt/6/tst
/mnt/NAS.20071201.204045/Archive

But actual run does not remove any files on destination.

==> smbmount <diskstation> /mnt/NAS.20071201.204156 -o

==> rsync -avhz --delete --progress /mnt/6/tst

If I use rsync to sync directories within my server everything works fine
and old files are deleted without problems.
  rsync -avhz --delete --progress /mnt/6/tst/ /mnt/6/tstdest/

rsync  version 2.6.9  protocol version 29

Have I found a bug, or what am I doing wrong???
