Created attachment 7372 Fix crash when systray is empty Crashes with message Gtk-ERROR **: GtkBox child XfceSystrayBox minimum width: -1 < 0 for height 1 The problem is that it returns -1 in systray_box_get_preferred_width/height functions. The best way to reproduce it is to change panel orientation with empty systray. I'm attaching the patch which fixes this.
