Aperture falls over loading images

Question

I've searched extensively and can't find my specific problem discussed.
When recently attempting to select a previously-developed image from my library, the 'loading image' message displayed for 20-30 seconds before Aperture crashed. After repeated experiences of this, I deleted the master from the library, reloaded it from my archive, and reapplied my adjustments. I quitted then restarted Aperture and the had the exact same problem with the image.
Now I find I have another adjusted image giving the same problem, and I'm worried there are more waiting to be discovered. There's no apparent corruption in the original (Canon CR2) image file, but it seems Aperture may be corrupting them in the adjustment process somehow.
Is this a known problem? Is there a fix or workaround? Thanks in advance for any assistance or suggestions.

Have you tried the open the photo in another application? Sometimes the image file is corrupted from the camera. I have a few image files that Aperture, Photoshop...cannot work with from the same card.
The workaround is to open the thumnail of the RAW with Preview and taking a grab from it and work with that. Not a very good solution but it works if the grab is huge like from a 30" monitor. If the photo is a vertical shot rotate it to a horizontal first prior to the grab.
