ubuntu 16.04, kde plasma 5.6.5, kde frameworks 5.23.0, qt 5.5.1 This is a pretty new installation. I'm using some other themes and stuff, but really not much changed.

I have the same after upgrading from kubuntu-ppa/backports. I've submitted it also to launchpad - https://bugs.launchpad.net/kubuntu-ppa/+bug/1626590. Perhaps it's bug in packaging.
Turns out it wasn't a bug. I've ran sudo apt full-upgrade and it's fixed now. The problem was that I used sudo apt upgrade instead and it didn't upgrade few packages.
