title: AVAudioPlayer currentTime issue
body: <p>I'm trying to use the <code>AVAudioPlayer</code> with a slider in order to seek into a track (nothing complicated).</p>
  
  <p>But I have a weird behavior... for some value of <code>currentTime</code> (between 0 and trackDuration), the player stop playing the track, and goes into <code>audioPlayerDidFinishPlaying:successfully:</code>
  with successfully to NO. And it did not go into <code>audioPlayerDecodeErrorDidOccur:error:</code></p>
  
  <p>It's like it can't read the time I'm giving to it.</p>
  
  <p>For exemple the duration of the track is: 295.784424 seconds
  I set the <code>currentTime</code> to 55.0s (ie: 54.963878 or 54.963900 or 54.987755, etc... when printed as %f).
  The "crashes" always happen when the <code>currentTime</code> is 54.987755... and I really don't understand why...</p>
  
  <p>So if you have any idea... ^^</p>
