OK, now I'm seeing the following error when I run the demo for
colorbar:

  colorbar example 13: failed
  binary operator `==' not implemented for `cell' by `matrix' operations

(this is just one of a number of demos that now fails).  Running the
example by hand, I see that the failure happens on the call to
subplot(2,1,2), at this point:

      objpos = get (child, "outerposition");
      if (objpos == pos)

The problem is that objpos at this point is the cell array

  {
    [1,1] =

       0   0   1   1

    [1,2] =

       0   0   1   1
  }


I don't know what the proper fix is.
