The bug is fixed in Debian jessie. Lenny works, too. I don't test squeeze.

If the isc-dhcp-server (ipv4) don't remove the DNS-entry, for example the
isc-dhcp-server -6 (ipv6) can't add DDNS with the same hostname. There ist
no request send to bind.

Useing ifdown and ifup at the client, then isc-dhcp-server updates
the ddns-entry.
