MSDN documentation says many things... most of them wrong. ;-)
(only slightly exaggerated, given Wine's experience with MSDN "correctness"
over the years)

IOW, I severely doubt that this is indeed the way Windows behaves,
otherwise it'd have been fixed in Wine a long time ago already since
apps would rely on and fully expect this behaviour of such a central
and important function.

Most likely you encountered application misbehaviour (feeding a NULL parameter
to a function expecting non-NULL) due to a different Wine bug which thus
caused the app to mis-step.
Would be interesting to figure out why this happened (e.g. via +relay trace).
