Application: systemsettings5 (5.5.4)

Qt Version: 5.5.1
Operating System: Linux 4.1.15-8-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
When I click the "play" button (I'm not sure on what is it actually supposed to do, but I presume it should demonstrate the effect) in an effect field, the System settings application crashes. I am using a czech localization of KDE so the names might slightly differ.

The crash can be reproduced every time.

-- Backtrace:
Application: Nastavení systému (systemsettings5), signal: Segmentation fault
