Unfortunately the backtrace is missing debug symbols. If you are able to reproduce please install debug symbols and attach a new backtrace. Without we cannot see where exactly it crashes.

Comment 2 Vincent A Pisciotta 2016-10-06 00:48:57 UTC

problem is resolved since:
kwin-5.8.0-1.mga6, systemsettings-5.8.0-1.mga6
