    region: Avoid a crash on panel destruction
    
    GtkListBox might emit the row-selected signal while being destroyed
    and our row-selected handler accesses widgets owned by GtkBuilder so,
    depending on the order on which the builder destroys its objects, we
    could crash on the signal handler when destroying the builder.
    
    Using g_signal_connect_object() avoids this issue by disconnecting us
    before our finalize() runs.
