Adobe Reader error with PDF/A: Invalid ColorSpace

Hello,

I report an Adobe Reader error when reading a PDF made as PDF/A with PDFCreator v2.0.

This is in French but the reason can be understood by English people:

Adobe Reader
(!) Une erreur est survenue lors du traitement d'une page. ColorSpace incorrect.

Note that the problem occurs with the 3 parameters of PDF Model-colors (RGB, CMYK and Greyscale).

The Adobe Reader XI is a version 11.0.09.

Thanks for your attention.

Regards.
