In short, it isn't actually possible to have a "static property".
Properties belong specifcally to an a instance of a GObject derived
class. You can actually return class (static) data when a property is
requested, but you still need an instance of the type in order to
execute the getter method.
In this case I would suggest write the method to get the instance by hand.
As to the error message, I'm not sure why that happens either - if you
remove that bad line you'll find value won't complain at all, but the
generated C won't compile. I guess the strangeness is probably down
to using pointers - unless you have a specific need, I would just use
references.
