deja.com has a whole bunch of stuff about this; it's not new or necessarily incorrect, but it's definitely not a -stable issue. The answer is quite simple; two network cards attached to the same physical network. It's not the real or fake IPs, it's that the arp packet gets to the kernel via a different NIC than it thinks it should and it's assumed that different interfaces go on different networks. I can easily reproduce this.
