I found the following bug, but I'm completely sure that is a LyX bug.
I'm writting a spanish text (Format/Document/Language/Spanish)
with a list item.
The text is the following:
Conexiones_no_persistentes. ...
The underscore represent a protected space. The dvi's page show
an n~ (ñ) instead a space.
Conexionño persistente. ...
If I try with default language works ok.
I exported to LaTeX and something like that appears:
\item [Conexiones~no~persistentes.]
The problem is that LaTeX interpret ~n like a ñ (n tilde), and
precede to protected space on lyxlist.
Sorry, but I can't sent to you a fix for that, just the error.
My document exported to LaTeX looks like:
------------
\documentclass[12pt,oneside,spanish]{book}
\usepackage{pslatex}
\usepackage[T1]{fontenc}
\usepackage[latin1]{inputenc}
\usepackage{babel}
\usepackage{setspace}
\onehalfspacing
\makeatletter
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% LyX specific LaTeX commands.
\providecommand{\LyX}{L\kern-.1667em\lower.25em\hbox{Y}\kern-.125emX\@}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Textclass specific LaTeX commands.
\newenvironment{lyxlist}[1]
{\begin{list}{}
{\settowidth{\labelwidth}{#1}
\setlength{\leftmargin}{\labelwidth}
\addtolength{\leftmargin}{\labelsep}
\renewcommand{\makelabel}[1]{##1\hfil}}}
{\end{list}}
\usepackage{verbatim}
\makeatother
\begin{document}
\begin{lyxlist}{00.00.0000}
\item [Conexiones~no~persistentes.]Problem.
\end{lyxlist}
\end{document}
------------
On LyX appears as:
\layout List
\labelwidthstring 00.00.0000
Conexiones\SpecialChar ~
no\SpecialChar ~
persistentes.
Problem.
