  File: /tmp/buildd/notify-osd-0.9.35daily12.11.28/egg/egg-alpha.c
  Function: egg_ramp_dec_func
  Code snippet:
  506 
  507   timeline = egg_alpha_get_timeline (alpha);
  508 
  509   current_frame_num = egg_timeline_get_current_frame (timeline);
  CID 10934 - DIVIDE_BY_ZERO
  On this path, function call "egg_timeline_get_n_frames(timeline)" has return value of 0
  Assigning: "n_frames" = "egg_timeline_get_n_frames(timeline)".
  510   n_frames = egg_timeline_get_n_frames (timeline);
  511 
  CID 10934 - DIVIDE_BY_ZERO
  In expression "(n_frames - current_frame_num) * 65535 / n_frames", division by expression "n_frames" which may be zero has undefined behavior.
  512   return (n_frames - current_frame_num)
  513          * EGG_ALPHA_MAX_ALPHA
  514          / n_frames;
