#8 assertion failure for null blob value

[lplatypus]

When the translation for blob types is set, a null blob value can cause the following assertion failure:

python: _kiconversion_type_translation.c:804: dynamically_type_convert_output_ob
j_if_necessary: Assertion `data_type == 520 ? !((converter)->ob_type == (&PyDict
_Type) || PyType_IsSubtype((converter)->ob_type, (&PyDict_Type))) : 1' failed.

Attached is a patch to fix this problem.
