    cheese: Fix assert failures when taking a photo
    
    Before this patch, cheese would log the following each time the user takes
    a photo:
    
    (cheese:21719): GLib-GIO-CRITICAL **: g_file_info_get_size: assertion `G_IS_FILE_INFO (info)' failed
    
    (cheese:21719): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed
