Public bug reported:

Binary package hint: gnome-settings-daemon

Yet more core GNOME desktop components failing!  gnome-settings-daemon
now joins nautilus and gnome-panel as apps that just can't keep running
for very long.

This is a similar trace to nautilus in #620323.   Although since nobody is
