Help in tracking Touch crashes w/quicktime?

We’ve been having 5 different machines now where Touch suddenly crashes. It’s a file mainly devoted to playing audio.
In one instance only I was able to get a .dmp and crash files, but Derivative says the only thing they can gather from that is that it was a quicktime call.

I need to find out why Touch is crashing in the next few days, and fix it.

Does anyone have experience to share with crashes related to quicktime calls?

I really need to find out what to look for.
