Digged a little deeper on the Ruby side of code -- and found a way to get 
(at least) some sample apps to run:

This avoids invalid indexes while producing the following output:

Don't know enough about Qt yet to say if this gives me a usable binding or 
brakes some important classes...?

Kind regards,
