Blender 2.54 beta Crashes Upon render.

Hello,
(sorry if this is in the wrong place, but i couldn’t see a troubleshooting thread)
I have been working on an animation that involves shape keys and loc and rot keys. I finished the shape keys first, and Blender was rendering fine, but after finishing all the loc and rot keys, every time I try to render the animation, without fail, Blender crashes. Once I managed to render a picture, but all other times it hasn’t worked. It always seems to crash on “raytree, building.” This isn’t a problem with my Blender because I have made test files that work fine. Im on Mac os 10.4.11 Blender 2.54 beta. I’m not sure if it would help but I can give you the troubleshoot report file, it’s really long so I won’t post it in the thread, but if you need it let me know.
Thanks heaps for your help!

Anybody?

I you’re using the compositor, make sure any viewers are deleted and the backdrop is unchecked before rendering animations (doesn’t seem to affect rendering of stills). This sometimes crashes renders in 2.54, was discussed in the bug tracker a while ago – details here:
