Comment 15 for bug 1773148

The fix is applied in .31, but the crash was still be observed once:
https://errors.ubuntu.com/?release=Ubuntu%2018.04&package=systemd&period=month&version=237-3ubuntu10.31

This seem to have been misreported against the version, since the ExecutableTimestamp is 1567655991 (date -d @1567655991 : Thu Sep 5 03:59:51 UTC 2019) , which matches the timestamp of /lib/systemd/systemd-journald in 237-3ubuntu10.29 .
