Keynote bug: Spontaneous reboots

Despite Keynote's maturity, a significant bug remains. Several users are reporting that pressing the "Play" button after composing a project causes the machine to immediately reboot.

From what's been reported so far, it seems to be limited to laptops, specifically iBooks and MacBooks, with and without an external monitor attached. At this point, no fix has been found.

Have any of you experienced this problem? Can you lend a hand in the troubleshooting?

Thanks, tipster!
