Looks like weston_desktop_surface_unlink_view() calls
weston_desktop_view_destroy() for the specified surface->view, and that
in turn will call weston_view_destroy() on the view (if it is
parentless), and then frees it.
So, you're right, the view is definitely going gone once
weston_desktop_surface_unlink_view() is done, and can't be used by any
subsequent calls.

This fix is okayed to land for the release, and can be landed either
pre- or post- beta.
