This is an attempt to fix #12333 where from the look of the trace, the segfault may happen if it tries to dereference a NULL view->priv->shell whereas we have a view->priv->cursor_image. Even though I couldn't reproduce, I'm wondering if it may possible to have no active image display while the cursor is indeed hovering an image. Furthermore this updated code is more logical anyway, because we should use the "show all" value from the actual display shell the cursor is hovering, not from the active display shell.
