TRAP: FailedAssertion("!(ndim < 6)", File: "plpy_typeio.c", Line: 686)

The assertion looks like this:

    if (ARR_NDIM(array) == 0)
        return PyList_New(0);

    /* Array dimensions and left bounds */
    ndim = ARR_NDIM(array);
    dims = ARR_DIMS(array);
    Assert(ndim < MAXDIM);     <-----

I believe that's wrong, it should be "ndim <= MAXDIM". Looks like I 
introduced this in commit 94aceed317, in v10.

I'll go fix that...
