Upgraded to Monotouch 4.1 Beta and get exceptions when reading SQL Lite DB

I have just upgraded to Monotouch 4.1 and all of a sudden I'm getting errors like the one at the bottom of the question when accessing my SQLite3 DB. Can anybody point me in the right direction what could be wrong here?

The code that is causing it looks like this:

using(SqliteConnection oConn = this.CreateDBMSConnection())
            {
                using ( SqliteCommand oCmd = new SqliteCommand ( "SELECT Local.*, LocalObjects.intID AS intIsPopulated FROM Locals" + " LEFT JOIN LocalData ON LocalData.intID=Local.intRootObjectID", oConn ) )
         开发者_高级运维       {
                    oConn.Open (  );
                    using ( var oReader = oCmd.ExecuteReader (  ) )
                    {
                        while ( oReader.Read (  ) )
                        {
                            Local oLocal = this.GetLocalFromReader ( oReader );
                            aLocal.Add ( oLocal );
                        }
                    }
                    oConn.Close();
                }
            }
