Obviously this wasn't the answer... There _is_ a corresponding Py_DECREF in
sipParseArgs(), it's just not called in a couple of cases (namely
qt.QListView.ensureItemVisible and friends). The corresponding code gencode.c
that emits the signature used in sipParseArgs() seems to be backwards with
respect to sipParseArgs though. "-" in gencode.c means no decref (according
to the variable name) but means decref in sipParseArgs.

I'm really not sure what's meant to be going on here; as far as I can see,
there's no reason to play around with the refcount of the argument tuple.
