I'm not sure why you would really want to do this -- is there 
really no alternative but to lay out the network this way?

Anyways it looks like what is happening is the router trying to
do proxy arp is (correctly) considering a /32 (the arp entry)
be a more specific route than the /29, and the /32 refers to
itself, so it balks. That said sending out an icmp redirect to
itself is almost certainly the wrong thing to do in this situation
(icmp ttl-exceeded might be more correct).

You might try, since the subnet is so small, putting individual
host routes to match the proxy arp entries. It looks like arp puts
a network route, and host routes seem to take precedence. (What is
the real difference between a host route and a /32 anyway?).
