Comment 12 for bug 2015857

This behavior is only noticeable on log-out. Killing gnome-shell works. I am using the 0001-apport-Write-coredump-at-beginning-and-quit.patch with a delay of 0.005s:

```
$ killall -11 gnome-shell
$ tail /var/log/apport.log
ERROR: apport (pid 15107) 2023-04-19 13:53:03,089: called for pid 14206, signal 11, core limit 0, dump mode 1
