dbversion crashes with the following stack trace if FluentNHibernate isn't able to load the correct connection driver. If possible it should detect the problem and provide a more user friendly error message.
Unhandled Exception: FluentNHibernate.Cfg.FluentConfigurationException: An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail.
* Database was not configured through Database method.
