5d overexposed in Aperture bug

Here is a link to an example image of what is happening. Everything, including camera (Canon 5d MkI), are set to default ie no user tweaked parameters. The dpp version is very similar to the embedded jpg (and the original scene). This embedded jpg was visible the first time in aperture for a second until it was 'rendered' by aperture to the pale imitation of the original. Lightroom also renders it correctly.

g5 2*1.8 Mac OS X (10.5.8) mbp 2.4 10.6.2 Aperture 2.1.4

I have submitted this via aperture feedback.
