I can also reproduce this issue in Chrome 13 Canary with my demo
http://hildr.luminance.org/Platformer/Platformer.html. getImageData returns
a correctly-sized buffer, but all the values are always 0. This makes it
impossible to do pixel manipulation with canvas (luckily my demo only uses
it for a visual effect, so at present I am able to detect the bad
getImageData and bail out.)

Browsers with working getImageData will display yellow crystals in the
platformer demo; Chrome 13 displays white ones.
