[Tex/LaTex] What does the following error message mean? `Undefined control sequence. \@Keywords l.4319 \ProcessKeyvalOptions{Hyp}`


I got the following error message (Setup: Ububtu 14 LTS, TeXmaker, TeX Live 2013/Debian, pdfLaTeX):

log-file says:

! Undefined control sequence. <argument> \@Keywords l.4319 \ProcessKeyvalOptions{Hyp} 
The control sequence at the end of the top line of your error message was never \def'ed.

hyperref.sty says:

        \ltx@gobble{end for xspace}%

Any idea what it means?

The error messages means, that \@Keywords is undefined.

\@Keywords is only defined by the class DissOnlineLatex, if \Keywords is used:


\Keywords is invoked at the end of metadata.tex and should not be deleted. Set the appropriate keywords there.
