NetworkManager uses plugins to read/write system-wide ("Available to all 
users") connections.
On Ubuntu, you use probably ifupdown and keyfile. You can check this in 
/etc/NetworkManager/nm-system-settings.conf

IPv6 support was added to 'keyfile' plugin just little time ago.
(git commit: a74e2cfde052120753bd2050fb9a7a1dc79e8a8f, 8 Jan 2010).

So update NetworkManager. Without that, you are not able to read/store IPv6 
system connections.

You can see debug messages in /var/log/daemon.log.
