Plasma workspace seems to restarts

[mario]

Hello all,
I'm running the new Kubuntu 17.04 live image as a Virtualbox Guest OS (live session, not installed). I'm playing around for testing new KF/Plasma features, and I got this strange behavior.
Steps to reproduce:
1) start the live session,
2) use some apps,
3) add a new Default Panel (now the desktop will display two panels)
4) from the panel on the top, go to the panel menu, and then choose Remove Panel (two notification will appear on the screen)
5) close the top notification with its red X

Now, the plasma workspace seems to restart, desktop and panels disappear for some seconds, while all opened applications remain running.

This behavoir seems to be reproducible on my environment, and *I think* is related to plasma-workspace or some other plasma stuff.
Sorry for any trouble about the report (first bug report here!)

Let me know if you need additional info.
Mario
