listings.sty with KOMA classes on TeX Live 2007-13 (Ubuntu 8.04, hardy)

When I tried to help somebody to solve a problem in the LaTeX Community Forum, I wrote a short test file, but it was not compilable though it contained just basic commands. I reduced it to the following minimal example:

\documentclass[a4paper,10pt]{scrartcl}
\usepackage{listings}
\begin{document}
\lstlistoflistings
\end{document}

It was not compilable with TeXlive 2007 on Ubuntu Linux 8.04, the error message was:
! Undefined control sequence.
\lstlistoflistings ...\lol@heading \@parskipfalse
    \@parskip@indent \@startto...
l.5 \lstlistoflistings

After examining listings.sty it seemed to be just a compatibility issue: the listings version 1.3 of 2004/09/07 distributed with the texlive-latex-recommended package of Ubuntu Linux 8.04 (hardy) just doesn’t work with the scrartcl class of KOMA-Script v2.95b (2006/07/30) that comes with TeXlive 2007-13.

For instance scrartcl.cls v2.8 used \@parskip internally together with the parskip/halfparskip/parindent options, but that’s been changed.

After installation of version 1.4 of the listings package by the MiKTeX package manager the compilation was successful.

The line

\@parskipfalse\@parskip@indent%

of listings v1.3 had been changed in v.1.4 to

\parskip\z@\parindent\z@\parfillskip \z@ \@plus 1fil%

I’ve sent a bugreport by launchpad expecting that the new version of listings.sty will be distributed with the texlive package soon.
