gimp/app/display/gimpcursorview.c
Jehan b13d4d9d17 app: use the "show all" value of the shell where cursor_image is displayed. 
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.
