Indeed, that did the trick.

I made the same observation -- in fact, I added an inlined wrapper function
to the affected class (I'm using C++):
    virtual void move_to(double x, double y) {
        move(x - pos_x, y - pos_y);
    }

Having this in the GnomeCanvas library itself, however, would be a very nice
thing.
