Thank you for taking the time to report this bug and helping to make Ubuntu better.
The format of /etc/network/interfaces for bonding interfaces appears to have changed in order to avoid a race condition. I think you might be falling on the wrong side of the race. Please see /usr/share/doc/ifenslave-2.6/README.Debian.gz, or online at:
I think the real bug here is that there is no automatic upgrade path regarding this change, or documentation in a place that users can spot before upgrading.
Unfortunately I think it's too risky to try and add an automatic upgrade path this close to release as it would not receive sufficient testing. The workaround is to fix up /etc/network/interfaces to the latest syntax by hand.
