Good find.  I added these lines to the end of your do_size_allocate()  
and it started working fine on both the old and new gtk+:

    $self->allocation->x ($allocation->x);
    $self->allocation->y ($allocation->y);
    $self->allocation->width ($allocation->width);
    $self->allocation->height ($allocation->height);

There's a comment in GtkWidget.xs that says "return the allocation as  
a read-only rectangle", but i think that goes back a very long way to  
the days before GdkRectangle had mutators.


I always thought that the size-allocate signal was supposed to be  
emitted from a wrapper that applied the changed allocation after all  
the signal handlers had a go a modifying it, but apparently that's  
not true.
