SAFEARRAY is the only way arrays can be passed to IDispatch-based COM 
object, so plenty of people do use them.

I just added some double specific tests to the win32com test suite and 
I'm afraid I can't reproduce the problem.  I can reproduce a similar 
problem if typeinfo for the COM object isn't used, but that doesn't seem 
to be the case for you - the type info is being used in your example.

Sorry I can't be more help...
