I can not reproduce this crash with the following combinations systemsettings 5.4.1 + Qt 5.5.0 systemsettings 5.3.2 + Qt 5.4.1 If you can still reproduce the crash could you please install valgrind and then run valgrind systemsettings5 in a terminal, try to reproduce the crash and add here the valgrind output?
I'll test again with a newer version. But I think the issue might be related to the fact that the test system doesn't support OpenGL 2, which is now required by Plasma (Qt Quick 2), so it crashes.
