If you're willing to depend on dbus-python >= 0.80 (recommended):

	>>> bytearray = bluez_object.MyMethod(byte_arrays=True)
	>>> bytearray
	dbus.ByteArray('\x01\x02\x03')
	>>> issubclass(dbus.ByteArray, str)
	True

See http://dbus.freedesktop.org/doc/dbus-python/doc/tutorial.html#return-values-and-the-byte-arrays-and-utf8-strings-options for details.

If you badly need to be backwards compatible:

	>>> list_of_bytes = bluez_object.MyMethod()
	>>> list_of_bytes
	dbus.Array([dbus.Byte(1), dbus.Byte(2), dbus.Byte(3)], signature='y')
	>>> stringified = ''.join(map(chr, list_of_bytes))
	>>> stringified
	'\x01\x02\x03'
