When I open Desktop behavior configuration (translated to english) and then Desktop effects, everything is OK and I can see list of the effects. Then when I close the window with Desktop behavior configuration and open again it and going to Desktop effects whole SystemSettings crashes. It is fully reproducible. Reproducible: Always Steps to Reproduce: 1. Select Desktop behavior configuratinon/Desktop Effects menu. 2. Close the window. 3. Open Desktop behavior configuratinon window again and select Desktop Effects Actual Results: Crash Expected Results: Do not crash I can see this bug for long time with KDE 5.
I can reproduce it every time on Archlinux, both with Intel and proprietary Nvidia drivers. However, I cannot reproduce it on a Tumbleweed virtual machine with Plasma 5.5.2 and KF 5.17. On Arch I don't have debug symbols for the backtrace, so I'm only going to attach the valgrind log for now.

Weird, the crash does not occur on a fully upgraded Fedora 23 (Intel graphics + plasma 5.5.4 + frameworks 5.18). Sounds like an Archlinux-specific issue?
