GObject speed up causes gtk3 apps to crash :(
gtk_check_button_init does this:
- Connect to notify::draw-indicator
- Change the draw-indicator property
- Continue to set up innards of the widget that the signal handler relies on
Previously, GObject would freeze notification until g_object_new returns. Now, we don't, since there is no notify handler at the time that we check, so we don't create the notify queue and g_object_notify will just emit notify right away (since at the time it is called, there is a signal handler).
