If an attribute has no value, `DataAlgo::fromUSD()` returns `nullptr`, and we were dereferencing it. We could probably still use a `static_cast` here as long as we checked for null, since we don't expect anything but StringData when non-null. But since I failed to predict this outcome, I've gone belt-and-braces and used a `runTimeCast()`.
