--- Comment #75 from Martin Klapetek <mklapetek at kde.org> ---
Thanks, pasting it here. Always please either attach the file here or paste it
directly here, pastebins tend to disappear. That said, your backtrace looks
absolutely normal, there's nothing wrong going on (in fact there is /nothing/
going on). Are you sure this is when the kded5 process is eating the cpu?
