General ⇒ Error while using \linebreak inside a heading

[AleCes]

Hello everybody, I'm experiencing problems in using \linebreak inside a \chapter[]{}. Minimal example below:

Code: Select all

\documentclass[a4paper, 12pt]{book}
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhead{}
\fancyhead[CE]{{\leftmark}}
\fancyhead[CO]{{\rightmark}}
\usepackage{fontspec}
\defaultfontfeatures{Style=Alternate, Mapping=tex-text}
\setmainfont{FreeSerif}
\usepackage{polyglossia}
 \setmainlanguage{serbian}
\setotherlanguages{french, latin, english, german, croatian, italian}
\usepackage{xunicode}
\usepackage{xltxtra}
\usepackage{bookmark}
\raggedbottom

\usepackage[center]{titlesec}
\usepackage{enumitem}
\setlist{topsep=0pt}

\setlength{\headheight}{30pt}
\renewcommand*{\thesection}{\arabic{section}}

\begin{document}
\tableofcontents

\chapter[Оснивање Цариграда и постанак источног римског царства \linebreak  (330\hbox{-}518~г.)]{Оснивање Цариграда и постанак источног римског царства (330\hbox{-}518~г.)}

\end{document}

Error message:

Code: Select all

You can break the line with \\. Not sure if that will fix the error you get.

Code: Select all

\documentclass[11pt]{report}
\begin{document}
\tableofcontents
\chapter[Some text\\some other text]{Some text\\some other text}
\end{document}

Why do you want to force that line break at all in a heading? That's bad style.

\\ doesn't justify the text, it just breaks the line.

The break is intended for the TOC, because there's an overflow there, not for the heading.

[…] The break is intended for the TOC, because there's an overflow there, not for the heading.

That's not the default behaviour. And you are not using hyperref by chance? If so, use its breaklinks option, which is described in Section 3.3 of the package manual.

If that doesn't help, prepare a self-contained and minimal example that exactly reproduces the undesired behaviour. There could be various other causes.

What do you mean by that? That by executing my minimal example you don't get the same error message as I do? And by the way, I use bookmark not hyperref, as you can see from my minimal example, which you seem to dismiss without even having taken a look at it.

P.S. Maybe you can't reproduce the error because the TOC is absent in the minimal example, I've now added the relevant command, please give it a try now.

Please accept my apologies. I mixed things up. I should really give up writing different posts simultaneously.

The problem is fixed if you delete the \hbox commands in the heading.

Apologies accepted, don't worry, I know you have to put up with so many posts.

The problem is fixed if you delete the \hbox commands in the heading.

This is no solution: if I remove \hbox{-}, and leave a simple hyphen in place, the date will be split and that is unintended.

What about either customizing the ToC itself or the page geometry?
