The fix for bug 1008965, uncovered a bug in glib: https://bugzilla.gnome.org/show_bug.cgi?id=719402 .
This is currently just issuing a critical warning:
(gnome-settings-daemon:13060): GLib-GObject-CRITICAL **: g_signal_emit_valist: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed
but it's potentially a crasher.
We can consider taking this into F20 final - do you think it's likely to be less dangerous to try taking the patch through freeze, or leave it alone and hope it doesn't crash anything?
I think the fix is safe enough to go into final.
OTOH, nothing else seems to be hitting this issue and AFAICT, this bug has existed in glib for 2 years now.
glib2-2.38.2-2.fc20 has been submitted as an update for Fedora 20.
Discussed at 2013-11-27 freeze exception review meeting: http://meetbot.fedoraproject.org/fedora-blocker-review/2013-11-27/f20-blocker-review-3.2013-11-27-17.01.log.txt . Accepted as a freeze exception issue because, uh, I don't really know, but people voted +1.
