Description Rui Matos 2013-11-27 17:30:29 UTC
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.

Comment 1 Adam Williamson 2013-11-27 17:34:04 UTC
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?

Comment 2 Rui Matos 2013-11-27 17:59:57 UTC
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.
