if the destroy signal never gets called, it seems that the image never
gets destroyed.

try adding a FINALIZE method in your Gtk2::ScrolledWindow subclass, and
explicitely remove the image:

  sub FINALIZE {
    my ($self) = @_;

    warn "Inside finalize\n";

    $self->remove($self->{image});
    delete $self->{image}; # this should not be needed
  }

ciao,
 Emmanuele.
