[python-win32] QueryInterface fails with object passed from VB

[jose simas]

No worries Mark, many thanks for your help. I am using the default
interface instead which works perfectly. Going through the custom
interface would make the code cleaner but I am happy to live with this
if that means I can use python in the backend :-) I will post here if
I find the answer.

Have a good vacation.

Cheers
Jose
