Problema estranho com `longtabu`

Problema estranho com `longtabu`

Gostaria de compartilhar com vocês um exemplo bastante simples que o LaTeX não é capaz de compilar.

Eu uso o longtabuambiente fornecido pelo tabupacote. Estou usando comandos booktabsrecomendados na documentação do tabu.

\documentclass[11pt]{book}
\usepackage[a4paper,showframe]{geometry}

\RequirePackage[latin1]{inputenc}


\usepackage{booktabs}
\usepackage{tabu}
\usepackage{longtable}

\usepackage[english]{babel}

\begin{document}



\begin{footnotesize}

\begin{longtabu} to 0.75\textwidth{cX[L]ll}
% We use commands from 'booktabs' package because it is recommended by 'tabu'.
%
\caption[Short caption for index.]{Long caption to be shown at the top of the first page of the table.\label{tab:label}}
\toprule
Col 1 & Col 2 & Col 3 & Col 4\\
\midrule
\endfirsthead
%
\caption[]{(Cont.) Long caption to be shown at the top of the rest of the table.}
\toprule
Col 1 & Col 2 & Col 3 & Col 4\\
\midrule
\endhead
%
\bottomrule
\endfoot

\endlastfoot
% Now the regular content :

No .logarquivo recebo este erro:

! Misplaced \noalign.
\toprule ->\noalign 
                    {\ifnum 0=`}\fi \@aboverulesep =\abovetopsep \global \@b...
l.88 \end{longtabu}

I expect to see \noalign only after the \cr of
an alignment. Proceed, and I'll ignore this case.

! Missing } inserted.
<inserted text> 
                }
l.88 \end{longtabu}

I've inserted something that you may have forgotten.
(See the <inserted text> above.)
With luck, this will get me unwedged. But if you
really didn't forget anything, try typing `2' now; then
my insertion and my current dilemma will both disappear.

e muitos outros erros semelhantes. E o compilador não termina. Eu tenho que forçá-lo a parar.

O problema pode estar relacionado com captionfrases, pois se eu excluí-las, o exemplo é compilado e um documento próprio é produzido.

o que estou perdendo? Talvez seja uma pergunta boba, mas não consigo entender o que está acontecendo, então agradeceria muito a sua ajuda.

Agradeço antecipadamente.

Você se esqueceu de encerrar a legenda com um fim de linha \\. longtabué baseado no código deMesa comprida(vero manualpágina 1, segundo parágrafo), entãoo manual da mesa longana verdade faz parte da documentação do longtabu. A necessidade de \\legendas está documentada na página 11 desse manual.

Uma sugestão: se você adicionar uma linha

\tabulinesep=3pt

antes da mesa, você consegue um espaçamento melhor. Tente este:
