Aperture3.1 very strange replicable crashing procedure

Hi,
I've isolated a strange crashing situations with aperture 3.1:

It's append only on my macpro with Aperture window maximized (30" cinema display), on macbook pro the problem seems to not exist.

Working on a RAW photo with "viewer" view and applying "AutoLevel RGB" Aperture crash every time; only in viewer view with maximized window on 30" screen, not in full screen, nor in browser, nor in split view.

I'll attach in the links below a test library with the problem and a video showing the issue:
