Functions mbstreamwriter_dealloc() and mbstreamreader_dealloc() of 
Modules/cjkcodecs/multibytecodec.c uses Py_DECREF() to free stream 
attribute memory, but this attribute may be NULL if MultibyteCodec or 
MultibyteStreamReader constructor fails.

Simple fix: use Py_XDECREF().

Example:
>>> import _multibytecodec
>>> _multibytecodec.MultibyteStreamReader(None)
