Stopping the SlideShowView and playing it again after some changes crashes the library

[jmartinesp]

As I was doing some work on the demo, I found out that if you .stop() the SlideShowView and you .play() it again after changing its playlist with .setPlayList(), it will crash the library.

Logcat:
