Photoshop: Color profiles affect color picker when layer mask is selected

When using an icc profile that modifies the white point, the color picker does not allow the picking of "pure white" (aka 255, 255, 255 or 1.0) when editing a scalar mask channel.

To reproduce do the following:

Create a new ps document
Fill the background layer with a color (red, for example)
Convert the background layer to a "normal" layer that supports layer masks
Create a layer mask, and fill it with black (all the color information will be hidden)
Use an icc profile that changes the white point
Switch to the layer mask and try to select a pure white from the color picker. You will not be able to do so. As a result, you cannot paint back full opacity in the layer mask.

As a work around, try this:
Add an adjustment layer (anything will do, we are just interested in the layer mask of this layer). Turn it off.
Use the eye dropper tool to select a "pure white" from the layer mask. Now, even though the icc profile is still active, you will be able to use a pure white to paint into the original layer mask. This leads me to conclude that the color picker is the source of the problem (it needs to recognize that icc profiles should not affect colors selected when layer masks are highlighted).

I would be happy to attach a sample icc profile that shows the problem if needed, I just don't know how to do that within this form (it won't let me upload an icc profile or even a psd image)

This affects (at least) CS2, CS3, CS4, CS5, CS5.5, CS6

We need to see the profiles.

And converting from RGB to Gray does involve the RGB and Grayscale profiles of the document or your workingspace profiles.
