Reproducible: Always Steps to Reproduce: Go to: System Settings → Display and Monitor → Screen Saver → [x] Allow widgets on screen saver → [Configure Widgets...] Use default Analog Clock widget, or add other widget. I added Digital Clock, so that's example. - Right click on widget - Select "Digital Clock Settings" - Try to change something (for ex, check "Bold" in font category, or "Show seconds") Actual Results: Crash, KDE Crash Handler starts. Expected Results: See that widget is changed according to my setting. I use "Euphoria GL" screensaver, but checked with few other, and on "Blank Screen"
