I'm using AlphaX, the first line of fehler.tex

     %&mylatex

ensures that shell-escape is enabled.

Exactly.

You're right again, but I've tried to produce a minimal example to  
create the error message.

And again, that's true, changing

     \usepackage{auto-pst-pdf}
to

     \usepackage{pst-pdf}

produces the same message.  Even more minimalistic.  Even simpler:  
change

     \usepackage{auto-pst-pdf}

to

     \usepackage{pstricks}

will create even five of these warnings.
