Comment 1 Albert Astals Cid 2015-09-26 11:18:59 UTC 
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?
Comment 2 G360 2015-10-04 21:16:32 UTC 
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.
