Problema com título de capítulo longo e arsclassica

Question

Tenho um problema com o estilo arscalssica em combinação com a tese clássica.

O texto sob o título do capítulo começa sempre na mesma posição, independentemente do tamanho do título do capítulo, o que produz este comportamento feio:

O código que usei para gerar essa saída é realmente básico:

\documentclass[10pt,a4paper,twoside,openright,titlepage,fleqn,headinclude,footinclude,BCOR5mm,numbers=noenddot,cleardoublepage=empty,tablecaptionabove]{scrreprt}
\usepackage{subfig}
\usepackage[eulerchapternumbers,subfig,beramono,eulermath,pdfspacing]{classicthesis}

\usepackage{arsclassica}

\usepackage{blindtext}

\begin{document}
    \chapter{\blindtext}
    \blindtext
\end{document}

A compilação gera os seguintes avisos:

O comportamento está ok se eu não usar arsclassica, mas apenas classicthesis:

Answer 1

Tente redefinir o comando \formatchapterdesta forma:

\renewcommand\formatchapter[1]{%
    \setbox0=\hbox{\chapterNumber\thechapter\hspace{10pt}\vline\ }%
    \begin{minipage}[t]{\dimexpr\linewidth-\wd0\relax}%
    \raggedright\spacedallcaps{#1}%
    \end{minipage}%
}

MWE:

\documentclass[10pt,a4paper,twoside,openright,titlepage,fleqn,headinclude,footinclude,BCOR5mm,numbers=noenddot,cleardoublepage=empty,tablecaptionabove]{scrreprt}
\usepackage{subfig}
\usepackage[eulerchapternumbers,subfig,beramono,eulermath,pdfspacing]{classicthesis}

\usepackage{arsclassica}

\renewcommand\formatchapter[1]{%
    \setbox0=\hbox{\chapterNumber\thechapter\hspace{10pt}\vline\ }%
    \begin{minipage}[t]{\dimexpr\linewidth-\wd0\relax}%
    \raggedright\spacedallcaps{#1}%
    \end{minipage}%
}

\usepackage{blindtext}

\begin{document}
    \chapter{\blindtext}
    \blindtext
\end{document}
