Hi, consider this MWE, please:
\documentclass{scrartcl} \usepackage{lmodern, blindtext} \begin{document} \blindtext \end{document} If I run htlatex on this MWE, I still get lots of errors: (/local/texlive/2014/texmf-dist/tex/generic/tex4ht/scrartcl.4ht (/local/texlive/2014/texmf-dist/tex/generic/tex4ht/article.4ht ! Missing \endcsname inserted. <to be read again> \MessageBreak l.225 \:temp{rm} ? R OK, entering \nonstopmode... ! Undefined control sequence. \GenericError ... #4 \errhelp \@err@ ... l.225 \:temp{rm} ! Undefined control sequence. \GenericError ... \let \@err@ ... l.225 \:temp{rm} !

Too many }'s. \:tempa ...after \:gobble \string #3:\endcsname }} l.225 \:temp{rm} And so on. I'm using TeXlive 2014 and made an update recently (February 15), which included an update of tex4ht. KOMA-script is of version 3.15.1910 and from the current-repo, see here: http://www.komascript.de/node/1801 I'd be glad, if someone could test the MWE and tell me, whether it's a bug of tex4ht or of my installation.
