I ran this test in gdb on a real mips machine. When tracing through ags_machine_selector_popup_new it seems that the "keys" variable is never initialized and a garbage pointer is passed to gtk_widget_show_all. The variable is never initialized because this condition is false: (AGS_MACHINE_SELECTOR_SHOW_SHIFT_PIANO & (machine_selector->flags)) != 0 Thanks, James
