Public bug reported: Unfortunately not much more informations at this time but this is what I have.
1. At some point the gnome-settings-daemon will start utilising about 95% of one CPU core, iotop will show dconf-services hovering around 3 place and lsof will show show gnome-settings-daemon using .config/dconf/user. 2. This has happened five times now every time on a fairly busy system e.g Firefox and Chromium multiple tab some with active content like flash and html5, one or more virtualbox machines and a terminal or two. 3. the first three times were weeks apart but the last two was on the same day after a reboot for the kernel update. 4. sudo kill -9 PID of gnome-settings-daemon restores the system to normal. 5. Afterwards the .config/dconf/ folder will have several user.????? files. If you need me to collect specific information next time let know.
