methinks the error lies here:
	IN	NS	0.0.168.192.in-addr.arpa.
which should be
	IN	NS	my.name.server.
ie, not the entire reverse lookup zone.
the same applies to your SOA record, usually.
the hostname part should be a fully-qualified hostname, not an IP address

try changing the NS record in your reverse lookup zone to
@	IN	NS		fedora3.home.net.

see if that works
