Ah, got it, thanks for the explanation. Now when I know how it works, it
makes sense.
(I guess that I should have read the user manual before asking, since it
is explained there.)
However, I think the error messages could be improved. I am used to
modules working more or less independently from each other, and this
coupling is unexpected.

Now I get the same problem when importing a new photo in 4.0. It's fine
right after import, but as soon as I change something in the White
Balance module, I get the "while balance applied twice" warning, and in
Color Calibration it says "white balance module error".
I get this in the console:
-----
[color calibration] white balance error
[color calibration] white balance error
[color calibration] white balance error
[white balance] double application of white balance
[white balance] double application of white balance
[color calibration] white balance error
That's exactly the planned behaviour: if you want to use the color calibration
module, the white balance module should be set to "camera reference".
The reasoning behind that is that the demosaic module needs some form of white
balancing/camera correction to give a decent result, but the proper place to
correct for illuminant (aka colour of scene lighting) is later in the
pipeline.
For more precise information, you may want to check Aurelien Pierre's posts
and articles (on pixls.us iirc).
So, either leave WB module in "camera reference", correct white balance in
color calibration module,
or don't use the color calibration module for setting the white balance. You
can set the adaptation to "none (bypass)" if you want to use the other
possibilities of this module.
