xfdesktop crashes in g_type_check_instance_is_a() when monitor powered on


Description PaulD 2019-10-26 21:38:32 CEST
Nearly identical to bug 14927.  Xfdesktop crashes sometimes when I power *on* the monitor.  14927 seems to have been fixed and I haven't had this problem for a while.  But, since a recent distribution upgrade, I have noticed this problem a few times.  Neither power-manager nor xscreensaver has been able to control the monitor sleep in many years, and I haven't tried it recently, but that is why I have to turn on and off the monitor.  AMDGPU.
