Sorry, my previous response came from the completely wrong bag.

The second is right. PyString_FromString() increases the refcount of the
returned string, so you have to decref it after use.

PyDict_SetItemString() does its own refcount increase internally when it
stores the value, so don't bother about it at all when you think about what
refcounts you have to increase or decrease.
