Bug#803207: gnome-settings-daemon: uses far too much memory (5.5GB currently)

[Stephen Kitt]

Package: gnome-settings-daemon
Version: 3.18.1-1+b1
Severity: important

Dear Maintainer,

On my system, the instance of gnome-settings-daemon started for the
login session uses more and more memory as time goes by (even though
there's no activity on the login session). Currently, after two days,
it's using 5.5GB; the daemons in the user sessions are up to 644MB and
22.6MB respectively:

Before I restarted gdm3 g-s-d was using nearly 30GB (on a system with
32GB of RAM). At that point the system was pretty much unusable.

Please let me know what I can usefully do to help resolve this (short
of running valgrind...).

Regards,

Stephen
