Doesn't crash for me on 25809. Your crash may have been caused because of Flip4Mac and/or Flash. I would check to make sure you have the latest versions of those.
This doesn't crash for me either with the r25809 nightly or with my local debug build of r25810.

The bug seems to be in Flip4Mac (which is the only way to display the video, btw). I will report it to its developers and close this as INVALID.
