oops again, this time whe clicked Effects settings steps to reproduce: - open desktop behavior - effects - navigate back - open search settings - navigate back - open desktop behavior - click effects => crash
I followed your steps in comment #1 and can confirm that I also see the crash. Fedora, Plasma 5.4.2/KF5.14/QT5.5
