Very Short WAV files crash MediaPlayer (divide error)

[humdinger]

This is hrev54691, 32bit.

I cut down a WAV file again and again, making it shorter and shorter. When it got shorter than ~11 KiB, MediaPlayer crashed when trying to play it back:

thread 11073: playback manager

Attaching full debug report and a very short WAV (one of the Sounds contest entry).

For reference: ​Controller::_FrameDuration: "Here for example, it will return a duration of 0 if the audio clip happens to be shorter than one video frame at 25 fps", and that's used as divisor in some places, like _TimePosition in your crash.
