Please install the debugging symbols for the phonon-backend-vlc and provide a new backtrace. Also, we need to know the version of the backend you are using.

i ve just reported another bug where systemsettings crashs if i change the backend 4 times. * This bug it is nt annoying for me because i have to provoke it but maybe provides interesting informations to developers (maybe is related with other problem and will help to resolved more critical bugs)
i forgot the link of the other bug report: https://bugs.kde.org/show_bug.cgi?id=281123
