Okay, also having this problem, running AppArmor. The fix of installing the old package works, thanks @jsmith64.
Wondering what to do to get this resolved. Yesterday I did run gdb and saw this was for me actually a SIG_SEGV but I do not have a good backtrace as debuginfo is missing.
Also should this be an OpenSuse bugzilla issue or a KDE systemsettings bug?
