If you're still having problems with this, please file new, separate bugs (after confirming that ipv6 is indeed set to ignore for that particular connection) and provide at the very least /var/log/syslog (though that should get attached automatically if you use 'ubuntu-bug network-manager'). This is likely now hitting some devices which don't properly support ad-hoc.
