I am using gnome-system-monitor with XFCE. Today I noticed that it is not working anymore. It core dumps like this:
1# gnome-system-monitor
(gnome-system-monitor:66848): Gtk-CRITICAL **: 11:52:35.853: gtk_box_pack: assertion '_gtk_widget_get_parent (child) == NULL' failed
(gnome-system-monitor:66848): Handy-ERROR **: 11:52:35.892: gtk_window_set_titlebar() is not supported for HdyWindow
[1] 66848 trace trap (core dumped) gnome-system-monitor
I do not use it that often so that I can not tell when it stopped working.
When I login to gnome it works just fine.
The coredump with XFCE looks like this:
