gnome-settings-daemon high CPU usage and keeps overwriting .config/dconf/user

[Marinus]

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. (Works somtimes)
5. Afterwards the .config/dconf/ folder will have several user.????? files.

If you need me to collect specific information next time let know.

Happened again but this time no.4 did not work the gnome-settings-daemon was killed and "/usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background none" started maxing out the one CPU core. After awhile gnome-settings-daemon restarted and continued maxing out the core.
"sudo restart lightdm" did however bring the system back.
"sudo restart dbus" was tried one time it worked but killed the wifi all my running program survived at leased allowing me to save and reboot.

Mmm this may have something to do with using a Bluetooth numpad as the bug started happening regularly this week and only happens during working hours. I started doing data entry this week in a VM, using the numpad more than normal.

PS. Is it better or update the bug info here or in the comments?
