I get

this message

every few minutes on Kubuntu (KDE), and the panels disappear.

It restarts itself automatically, so it's not a real problem, just an annoyance, but it is a big annoyance.

I've tried sudo apt install --reinstall plasmashell plasma-desktop, but that made no difference.

When I try a backtrace from the error message, it says it's unable to produce a useful backtrace.

Try installing the latest version of Plasma as a backport:

sudo apt-add-repository ppa:kubuntu-ppa/backports
sudo apt update && sudo apt full-upgrade -y
