    Bug 795911 - GIMP crashed while I was undoing a gradient
    
    In the gradient-tool editor, when responding to an endpoint size-
    entry "changed" signal, make sure there is a selected handle, and
    bail otherwise.  We can receive a "changed" signal without a
    selected handle, if the endpoint is deselected while a change to
    the size-entry's value is in progress, causing the the tool GUI to
    be unmapped, and the changed value to be committed.
