Package: latex-beamer Version: 3.07-1 Severity: normal Tags: patch hi
here are two bugs, and patch; I submitted those also upstream ---as posted in https://sourceforge.net/tracker/index.php?func=detail&aid=2089504&group_id=92412&atid=600660 If a presentation uses \subsection, then the labels to successive frames have wrong numbers. In the code, there is a counter called 'subsectionslide' that counts the number of slides since the last \subsection; the bug is that, when \subsection is invoked, 'subsectionslide' is incremented by \refstepcounter, so this is what is (wrongly) associated to the \label. --- https://sourceforge.net/tracker/index.php?func=detail&aid=2089481&group_id=92412&atid=600660 When using \AtBeginSection, the labels to sections and subsections are wrong. The problem is that the LaTeX \section{sec3}\label{sec3} works by writing the content of [EMAIL PROTECTED] into the .aux file. But if \AtBeginSection[]{ \begin{frame}<presentation>[plain] \frametitle{Outline of section} \tableofcontents[currentsection] \end{frame}} is used, the 'frame' environment damages the value of [EMAIL PROTECTED] before \label can write it to .aux ----- The attached patch fixes both issues. I also attach a stress LaTeX file, that shows the bug, and that testifies that my patch works. a. -- System Information: Debian Release: lenny/sid APT prefers testing APT policy: (500, 'testing') Architecture: i386 (i686) Kernel: Linux 2.6.26-1-686 (SMP w/1 CPU core) Locale: LANG=it_IT.UTF-8, LC_CTYPE=it_IT.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages latex-beamer depends on: ii latex-xcolor 2.11-1 Easy driver-independent TeX class ii pgf 2.00-1 TeX Portable Graphic Format ii texlive-latex-base 2007.dfsg.1-3 TeX Live: Basic LaTeX packages latex-beamer recommends no packages. latex-beamer suggests no packages. -- no debconf information -- Andrea Mennucc "E' un mondo difficile.
