I'll have to workout the exact scenario the errir occurs. As a note there is many tests already that go through both cases, that appear to work just by chance under wine. While developing it, I attempted to use the TYPEFLAG_FDUAL flag but it caused a massive amount of test failures. Just the theory of the original code is just wrong, Not all interfaces can be an dispatch interface.
However TYPEFLAG_FDUAL is checked earlier, and I think it implies IDispatch support. But that's definitely needs a number of tests, not just for this one flag, but for different HREFTYPE values too. There is too many assumptions already making it impossible to follow, fix like that won't improve that but tests at least will offer some assurance.
