Ah, right - chaining only happens automatically when the exception has already been caught and moved to sys.exc_info.

There's a _PyErr_ChainExceptions(), though, which does it for you. You should be able to say

    PyErr_Fetch(&x,&y,&z)
    PyErr_SetString()
    _PyErr_ChainExceptions(x,y,z)

(does pretty much what your code does as well)
