[clug] samba messages and IPV6?

[Paul]

Since my update to Fedora 10
I've been noticing some messages in the syslog which looks like IPV6 
address, does anyone know what they mean and how can I fix them?
eg
 smbd[7830]: [2009/02/22 18:59:57,  0] lib/util_sock.c:get_peer_name(1870)
 smbd[7830]:   Matchname failed on home.server ::ffff:192.168.0.10

my RPM versions:

samba-3.2.8-0.26.fc10.i386.rpm
samba-client-3.2.8-0.26.fc10.i386.rpm
samba-common-3.2.8-0.26.fc10.i386.rpm
samba-swat-3.2.8-0.26.fc10.i386.rpm
samba-winbind-3.2.8-0.26.fc10.i386.rpm
system-config-samba-1.2.67-3.fc10.noarch.rpm
