Insertion of Data into WKB-Point Field causes error

Not yet worth a bug report, because could be define as "user input error", but:

INSERT INTOdatabase.table(name,ortWKB) VALUES ('sfgh', 0x35332E36333236342C392E3932303339);

/* SQL Fehler (1416): Cannot get geometry object from data you send to the GEOMETRY field */

INSERT INTOdatabase.table(name,ortWKB) VALUES ('sfgh', POINT(53.63264,9.92039));

/* Betroffene Zeilen: 1 Gefundene Zeilen: 0 Warnungen: 0 Dauer von 1 Abfrage: 0,029 Sek. */
