If source is a symlink you have to specify source/ otherwise you can get
something like this.

Illustrated:

> cd /tmp
/tmp ~
/tmp> mkdir x
/tmp> cp /boot/vmlinuz-2.6.3-amd64 x/
cp: kan nie stat `/boot/vmlinuz-2.6.3-amd64' uitvoer nie: No such file or directory
/tmp> cp /boot/vmlinuz-2.6.32-5-amd64 x/
/tmp> ln -sv x y
`y' -> `x'
/tmp> mkdir z
/tmp> rsync -av y z
sending incremental file list
y -> x

sent 40 bytes  received 15 bytes  110.00 bytes/sec
total size is 1  speedup is 0.02
/tmp> rsync -av y/ z/
sending incremental file list
./
vmlinuz-2.6.32-5-amd64

sent 2425012 bytes  received 34 bytes  4850092.00 bytes/sec
total size is 2424608  speedup is 1.00
