Sigma DPx (non-Merill) auto bracketing shots have incorrect white-balance...

Sorry I forgot to mention I am taking +/- 2 stops for HDR set.

If the shot was taken from an auto bracketing sequence (and not manually
set to +2), the broken color balance is due to a bug in all non-Merill
Sigma DPs: the correct white balance is only done for the correctly
exposed shot. In the following test the issue is shown in low-light shots,
but the white balance problem is true for normal light as well:

Note that this is fixed in the Merrill cameras.
