fs->ab: One problem here is that Impl_GetSupportedInterfaces does not catch
RuntimeExceptions (or any others) thrown during calling getTypes (or any other
UNO method). This is why it finally crashs. I suggest adding more robustness to
this code, else every UNO component has the potential to crash the whole
application.
fs->cl: The reason why the exception is actually thrown in queryInterface is
because SdDrawPage::getTypes allocates a css.uno.Type sequence which is larger
than actually needed. Thus, a "void" type is part of this sequence, and returned
as supported type. The Basic runtime then queries for this "void" type ...
Adjusting |nOwnTypes| in |SdDrawPage::getTypes| easily fixes the problem, I
think the reason is the fragile construct used in this method:
sal_Int32 nOwnTypes = 10; // !DANGER! Keep this updated!
Well, the DANGER hits here - 9 is what's really needed. May I suggest using
things like a vector::push_back and comphelper::concatSequences to make the code
less error-prone?
