Bug#899204: gnome-logs: Segmentation fault in gl_journal_update_latest_timestamp

Package: gnome-logs
Version: 3.28.2-1
Severity: normal

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

When GNOME Logs is started by a user unable to read system logs
(like in #866171), clicking any of the tabs in the pane on the
left will cause a segmentation fault. This happens regardless
of if X11/Wayland is used.

Just before crashing, it emits a warning:

(gnome-logs:8896): WARNING **: 15:12:43.616: Error retrieving the sender timestamps: Cannot assign requested address

Also, I can't reproduce this on 3.22.1-2 in Stretch.

I've included a backtrace as well.
