Bug#837781: mate-settings-daemon: assertion 'closure->ref_count < CLOSURE_MAX_REF_COUNT' failed

[Chris Chiappa]

Package: mate-settings-daemon
Version: 1.14.1-1
Severity: normal

My system has been engaging the OOM killer sporadically the last
couepl of weeks.  It started dragging this morning and I captured this
line from top:

2387 cchiappa  20   0 9128408 6.512g   2220 R  93.8 83.9   5:07.88 mate-settings-d

Killing mate-settings-daemon restored its memory to something that
looks reasonable:

cchiappa 14757  0.0  0.4 1228008 33248 ?       Sl   09:04   0:00 /usr/bin/mate-settings-daemon

It seem to be coincident with having about 3.2 million of these lines
in my .xsession-errors:

(mate-settings-daemon:2387): GLib-GObject-CRITICAL **: g_closure_ref: assertion 'closure->ref_count < CLOSURE_MAX_REF_COUNT' failed

Given that Bug#824950 also mentions a memory leak, perhaps there is a
general problem with errors leaking?
