screenshot of klipper startup messages and blank icon

After upgrading my workstation today, notification icons for kde applications
appear with a white square instead of their proper icon in the systray area of
xfce4-panel. I'm using the openbox window manager and the notification icons
that I'm looking for are those of kmix and klipper. I believe that the upgrade
caused a switch from kde4 to kde_plasma (kde5?).

Excerpts from /var/log/zypper.log:
