Hmm, interesting.  I, too, see this happening on a fully updated rawhide machine using NetworkManager:

$ uname -a
Linux ktmtoshiba 3.13.0-0.rc0.git7.1.fc21.x86_64 #1 SMP Tue Nov 19 02:18:43 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

$ ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.238.116  netmask 255.255.255.0  broadcast 0.0.0.0
        inet6 fe80::ca0a:a9ff:feb1:46c2  prefixlen 64  scopeid 0x20<link>
        ether c8:0a:a9:b1:46:c2  txqueuelen 1000  (Ethernet)
        RX packets 912190  bytes 1118290284 (1.0 GiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 257389  bytes 23661386 (22.5 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 1  collisions 0

It would appear to be in the interaction between dhclient and NetworkManager (which actually starts the nic and configures it,
dhclient or NetworkManager?) as my dhclient leases file also shows  a broadcast address but, as you can see, none appears on my nic.
 Seems like a bz should be raised for this.
