This has affected all Plasma 5 releases in Kubuntu since Utopic, including the current backport of Plasma 5.3.
It reliably triggers a cascade of crashes in at least krunner, plasma and kwin on every screen topology change, making for a very disconcerting user experience. Please consider cherry-picking https://codereview.qt- project.org/#/c/111100/ for Qt < 5.4.2, Fedora and OpenSUSE have already done so.
