[openstack-dev] SQLAlchemy 0.7.9 issue

I managed to fix the issue (explained at https://bugs.launchpad.net/nova/+bug/1086333) without modifying SQLAlchemy code. The issue can be fixed by calling session.begin( ) before calling the method save( ) and passing it the corresponding session instance. After  the fix is in place, the expected exception 'DBDuplicateEntry' is getting raised on adding a duplicate row.

Does this solution sound correct?

PS: The same solution can also be used for similar issues (such as security group creation LP #1093458).
