Seems to me like a bug in bmpx at line 1312. At both lines 1181 and 12000, the BMP_SYSTEM_CONTROL_SIGNAL_TRACKLIST_ITEMS_ADDED signal is defined to pass two arguments: an integer array, and an integer. However, at line 1312, the signal is emitted with no arguments. Try changing line 1312 to: g_signal_emit (G_OBJECT (control), signals[BMP_SYSTEM_CONTROL_SIGNAL_TRACKL= IST_ITEMS_ADDED], 0, added_rows, n_added_rows); And see if that helps.
