[pdftex] Two /Creator or /Producer entries

Hello,

there is a thread in comp.text.tex,
subject: problem with PDFTeX and hyperref

It should be possible to set the /Creator field, so I consider
this as bug of pdfTeX and not as problem of hyperref.
With version 1.00b I get two /Producer entries.

I think, the user (packages, ...) are responsible that not
many entries are given for the same key in \pdfinfo.
But if some keys are used in \pdfinfo, then pdfTeX
should suppress its own.

Back to the problem with the encrypting application:
For example, a small program can be written that
overwrites the wrong entry with spaces. (The size
must not change because of the xref table.)
