Bug#820527: gnome-settings-daemon: 100% CPU spin when /run/user/<UID>/dconf/user cannot be opened.

[Morten Neergaard]

Package: gnome-settings-daemon
Version: 3.18.2-1
Severity: important
Tags: upstream

Dear Maintainer,

when /run/user/<UID>/dconf/user is cannot be created, e.g. if the parent
folder is owned by another user, gnome-settings-daemon gets stuck on
trying to open the file. strace verifies this easily.

This appears to be the same as bug #818600, mate-settings-daemon cannot
create file /run/user/<UID>/dconf/user and fills up the memory. In
gnome-settings-daemon, however, memory usage stays constant and low.

Assuming this is an upstream bug which affects code common between the
two.
