--- Comment #2 from fedor.smile at gmail.com ---
Installed libkf5activitiesstats1-dbgsym, as you requested, and also intalled
kdelibs5-dbg (as it is stated as needed in
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/

Now the stacktrace looks like this:

Application: System Settings (systemsettings5), signal: Segmentation fault
