Hi
I have reproducible crash every time I exit from KDE System settings.
quick search in KDE bug track shows that it was already fixed:
https://bugs.kde.org/show_bug.cgi?id=355711

My crash output looks pretty similar to what described in that bug report

and this commit supposedly fixes it:

http://commits.kde.org/kparts/5ac5dfb28014035e3704ae8bf8076001e5955ceb


Thanks !

Tim
