-- Information about the crash:
- What I was doing when the application crashed:
I was trying to open a sub-menu of systemsettings5, it crashed before the submenu could appear  the bug only appear when in «icon-view mode» with a left-side pannel it seems to work properly.
- Custom settings of the application:
I installed Kvantum and used a custom theme found online, but I'm not sure it's related.

The crash can be reproduced every time.
