Yes systemd has crashed when it was updated.

But unfortunately I couldn't figure out why because we had the "good" idea to
disable coredump handling by default on Leap and strangely nothing was logged
in the journal...

So I couldn't any useful information about the crash.

So far we know:

 1. this happens when systemd is re-executed while being updated (v234 -> v234)
 2. it isn't 100% reproducible
 3. strangely the crash is not logged in the journal

Something that might be related: dbus and polkit are reloading their
configuration files while systemd is updated:
