-- Information about the crash:
I was copying a lot of data to a USB disk - all 4 CPU cores at 100% for several minutes. 
Grooveshark (gnash?) can not handle this. 
Normally is hangs  for a second or so, this time it crashed multiple times. 
Try reproducing by doing multiple large copy/move orders simultanious.
