Lightroom/Acrobat Pro/X: pdfs exported from the book module display incorrectly in Acrobat Pro and X.

When exporting as pdf from the book module, blacks are not black and some colors shift when viewing the pdf in Acrobat Pro/X. Confirmed on many setups. See the thread at: http://forums.adobe.com/message/4915281
I need to stress that this problem only occurs with Lightroom exported pdfs when viewed in Acrobat Pro/X. Acrobat Pro correctly displays pdfs from other applications and other pdf viewers (Apple Preview, Acrobat Reader) display the files correctly. It is not clear whether the issue is with Lightroom, Acrobat, or both but the issue makes the pdf exports unreliable.

It appears that LR is converting the image files to Blurb.icc CMYK profile and then to sRGB color space when Exporting to PDF with sRGB profile setting in the Book module. This causes a narrowing of the image color gamut, which can be seen when opening in Adobe Reader or Acrobat.

There is 2nd problem concerning how text fonts are color managed in the Book module Export to PDF. They are being exported as ProPhoto RGB color space, even though sRGB Color Profile is selected in the Book module. This causes the font color to shift in Acrobat and Adobe Reader, since the PDF is tagged as sRGB Color Space.

This is not fixed in LR4.3 Final Release and still remains an issue.

This problem is not seen in PDF files created using InDesign.
