Best I can tell, there is no reason it's not legal - it's just unusual :)
You could argue that we should just recurse away on VT_VARIANT until we find
a real type.  I was kinda hoping you had a legitimate case it was failing
with, as then it would have been clearer it was a bug :)  Particularly, the
top of that function has:

	/* skip past any variant references to a "real" variant 
	  (Why do we do this?  Why is it only a VARIANT?  whats the story,
morning glory?
	while ( V_VT(var) == (VT_BYREF | VT_VARIANT) )
		var = V_VARIANTREF(var);

but the code fails to gracefully handle the non-byref variant case, as you
found.  Oh well, some other day (or if someone is keen, a bug couldn't
