No, it doesn't help. I don't think it has to do with scope, but with 
constness.

I had a reply from vadim vk crocodile org saying that he had the same problem 
and fixed it by running a perl script on the generated code to change " const 
char * const " to " const char * ". I've confirmed that this works.

Now the question: which should be fixed, glademm or gtkmm?

Thanks,
John
