As I hinted, you need to patch the C library so that it doesn't do extra
stuff in the _new() function. New functions should just be sugar around
g_object_new().
Or you need to hand-code the c++ constructor in your .ccg file, and do the
same stuff there. That's not always possible, because it sometimes uses
private structs and functions.
If it's too much work to make the C object do this properly, you can
patch/ask to add a public *_construct(GdlThing*) function, but that's
ugly.

Yes. I should have this far before answering.
