Not understandable exception message

When you get an exception from NHibernate related to, let's say updating an entity that cause a Duplicate Key Violation on the DB, the exception message doesn't explain what happend. In this case you get a NHibernate.Exceptions.GenericADOException with the following message: {"could not insert: [Budano.Store.DomainModel.Article]
[SQL: NHibernate.SqlCommand.SqlCommandInfo]"}. This message is related to an application I am creating and the Article entity is causing a Duplicate Key Violation due to a unique index in the DB. The message must contain all details about the entity is causing the problem instead of [SQL: NHibernate.SqlCommand.SqlCommandInfo].
