However, MongoMetaRecord's Self type is
  MongoMetaRecord[BaseRecord] with BaseRecord
see <http://scala-
tools.org/mvnsites/liftweb-2.4/#net.liftweb.mongodb.record.MongoMetaRecord>
and <http://www.scala-lang.org/node/124>

So maybe try to add a self type as well or write
trait StructuredDbObject[BaseRecord <: MongoRecord[BaseRecord]]
      extends BaseRecord with MongoMetaRecord[BaseRecord]
or something?
