    Avoid assert when taking avatar photos too quickly
    
    If the take photo button was pressed while a photo was being taken, an
    assert would be triggered by the failed call to
    cheese_camera_take_photo_pixbuf(). Avoid this by setting the take photo
    button insensitive while a photo is being taken, and setting it
    sensitive after the photo has been taken. Fixes bug 699596.
