    Connect thumbnail nav button signals
    
    The thumb nav widget crashed when clicking the buttons to scroll the
    thumbnail view. This was caused by connecting to the wrong signals:
    âbutton-pressed-eventâ and âbutton-released-eventâ, rather than
    âpressedâ and âreleasedâ. There was also some duplicate code for
    creating the left button, which led to a GtkButton being leaked when
    the thumb nav was created. Fixes bug 660686.
