I have been bitten by a bug in Aperture 1.1.2. It sometimes exports images with parts missing. I've had halves and quarters missed out so far, just a few in hundreds of images. I suspect that Aperture renders using multiple threads or multiple parts of the GPU and somehow fails to reconstitute the image at the end. The worst part about this bug is that the file icon is complete, so unless you actually open up the image file an look at it you don't realize that the gaps are there. I spotted it because my thumbnail pages in the galleries were affected.

I'm running under 10.4.7 on an iMac G5. It has only done this since I started adjusting images.
