[Wayland-bugs] [Bug 73490] SIGSEGV in ping_timeout_handler

--- Comment #4 from U. Artie Eoff <ullysses.a.eoff at intel.com> ---
Another way to reproduce this is to SIGSTOP a wayland client (i.e. kill
-SIGSTOP <pid of client>), then move the mouse in and out of the client. 
Further inspection with gdb shows that the seat->pointer is being NULL deref'd.

Program received signal SIGSEGV, Segmentation fault.
0x00007f6b92f1aa13 in ping_timeout_handler (data=0x25f0970) at shell.c:1789
1789                    if (seat->pointer->focus &&
(gdb) print seat
$1 = (struct weston_seat *) 0x2558870
(gdb) print seat->pointer
$2 = (struct weston_pointer *) 0x0


NOTE: this issue only seems to happen when the "seat" option is specified in
the weston.ini for that output.
