KDE 4 is no longer maintained, but also the backtrace is missing any debug symbols. Could somehow be related to > previously force-quitted KDE but if it's a reproducible bug and you want to know about the cause, ensure to install debug packages for kwin to provide a full backtrace (it won't be fixed anymore, but maybe there's a workaround)
