--- Comment #2 from Michael Catanzaro <mcatanzaro at igalia.com> ---
Something's gone crazy wrong here. The AtkObject* axObject is non-null, and the ATK_IS_VALUE(axObject) check passes fine, but it has no class struct somehow, which is absolutely nuts. I guess it must be memory corruption somewhere, something somewhere writing zeros to the wrong place, because I don't think there's any other way a class struct could ever be NULL.
