This is not specific to iTunes 9, but has been happening since I updated to 8.2.1 a month or so ago. If iTunes is idle (open, but no music playing) for even a matter of minutes, it crashes and asks to send a report to Apple. I've sent in many reports a day for the last month, and was really hoping updating to 9 would solve the issue, but it is still happening. 
I'm running Leopard on a Mac Pro. Any ideas?
