Did you previously have a field named 'title' in this model that was marked unique, that you have since removed? If so, the column may still be in the database with a unique constraint. Since it's no longer in the model, some default may be being used when you save, and that's obviously not unique. Use suitable tools for your database (if PostgreSQL, I suggest PGAdminIII) to examine the schema. You may be able to drop the column, or at least the constraint (back up the database first).
If there never was such a field, then the problem originates in another model. You still may be able to figure it out by inspecting the database schema. You can also temporarily set up to catch the Integrity Error close to the origin, and call pdb.set_trace(), where you can examine the query to see what models are involved.
