[Bug 215897] Re: audacious crashed with SIGSEGV in ape_decode_frame()

[Kees Cook]

** Description changed:

  Binary package hint: audacious
  
  Rare crash of the new ape plugin. Apparently when automatically changing
  tracks in the playlist (from one whole-cd ape to the next one).
  
  Thread 1 (process 22296):
