o_o Gasp! Whenever I save in Blender, it crashes. Doesn’t matter if I just modeled a cube, or a 300,000,000 poly rainforest. It crashes upon all types of save and export. That’s really REALLY bad, seeing as Blender is my only modeling app, and the only one that really fits in my price range and has suitable features. It started happening when I installed Leopard, but I can’t find any other cases of this happening to people. I’ve also tried reinstalling it.
I don’t know if this will help, but did you see this thread on the Blender Artists forum?

Nope. D: Nobody seems to have this same issue. I don’t know why on earth it’d choose me to torment of all people. 
I don’t have Leopard so I’m not sure how helpful I can be, but here are a couple things you can try. I’m guessing that the problem may be either Python related or graphics driver related, but I’m only guessing. IIRC Leopard is now using Python 2.5, right? Perhaps you can try one of the new builds here:

Jens just posted a new build today that includes all the latest goodies and is built for Python 2.5. Maybe you’ll get lucky and it will work for you. If it doesn’t, I’d post at Blender Artists and the Blender dev forums. And I might also try an older build of Blender just to see if anything different happened.
Hope you sort it out…
That build worked! I had already tried the official Python 2.5 build to no avail, but in any case. Blender is back, and that means that I’m back! 
Thanks
Happy to have been of help!
