Error en rece1.py TypeError: write() argument must be str, not bytes

[fpizzichillo]

Estimados, buenas tardes.
Al intentar emitir una factura ya sea en homologación o producción obtengo el siguente error:

During handling of the above exception, another exception occurred:

TypeError: Object of type bytes is not JSON serializable

Lo ejecuto de la siguiente manera:
rece1 rece.ini /xml /json /debug --trace

Modificando la línea 451
de f.write(client.xml_response)
a f.write(client.xml_response.decode('utf-8'))
veo que funciona. No se si es la manera adecuada de resolverlo, pero a alguno puede llegar a servirle.

Saludos
