    Howdy.

    PDF-files are sometimes found faulty in arbitrary ways by
    GhostScript, when I try to transform them. The reported problems do
    rarely prevent me to proceed and I can ignore them.

    Today however, I am confronted to a PDF transmitted by my social
    insurance company, which does not look extraordinary at first
    glance, nor very big, but PDF-readers take unusually long to open
    it.

    There was no special reason to do it, but I handed the file to
    GhostScript for a transformation to monochrome via Tiff conversion,
    just to see what happens.

    I had not seen this error, before, maybe you know something about
    it:

    -------------------
    The following warnings were encountered at least once while processing this file:
    invalid operator used in text block

    **** This file had errors that were repaired or ignored.
    **** The file was produced by:
    **** >>>> iText 2.1.7 by 1T3XT <<<<
    **** Please notify the author of the software that produced this
    **** file that it does not conform to Adobe's published PDF
    **** specification.
    ----------------

    Relating the message to the iText developers will not be awfully
    useful. However, I have been looking for a way to do that. There
    is a lot of rCLSalesrCY and rCLBusinessrCY and rCLKnowledge BaserCY and I have given up to get in contact with them.

    Chances are, the difficulties have nothing to do with the error.

    Cheerio
