I experienced this too with fresh install of 13.04. The node is connected to a LAN with a router sending RA's with a global prefix. Even after updates the node did not generate a privacy address. /etc/sysctl.d/10-ipv6-privacy.conf shows both 'all' and 'default' to have a use_tempaddr setting of 2. When I cat /proc/sys/net/ipv6/conf/all/use_tempaddr and /proc/sys/net/ipv6/default/use_tempaddr the value is 2. However, the value of /proc/sys/net/ipv6/conf/eth1/use_tempaddr is 0.

After a fresh install the directory /etc/NetworkManager/system-connection is empty. If I open the graphical network manager tool a file called Wired Connection 1 is immediately created in that directory. And magically the value of /proc/sys/net/ipv6/conf/eth1/use_tempaddr turns to 2 and a temporary address is generated.
