dvipng should depend on latex-xcolor

[Shriramana Sharma]

I'm running Kubuntu Raring, with versions as below:
texlive-base: 2012.20120611-5
dvipng: 1.14-1build1

I have this simple document foo.tex:

\documentclass[16pt]{article}
\usepackage{amsmath,amssymb}
\usepackage{breqn}
\pagestyle{empty}
\begin{document}
$ \infty $
\end{document}

I do latex foo.tex and I get the .dvi files with no problems. Then I do:

dvipng -T tight -D 150 -bg Transparent -fg Blue -O 0cm,0cm foo.png foo.dvi

I get this:

This is dvipng 1.14 Copyright 2002-2010 Jan-Ake Larsson
Segmentation fault (core dumped)

gdb says there are no debugging symbols so I couldn't try that.

Due to this dvipng problem I am not able to use SymPyPrt (https://github.com/scios/IPyXt) on IPython2/3: https://groups.google.com/d/msg/sympy/WzwS3578TuU/sZAYDcFQ8cIJ

I did not have a problem with using SymPyPrt on Kubuntu Precise of last year, and I thought dvipng has practically not changed in Raring since Precise: http://packages.ubuntu.com/search?keywords=dvipng&searchon=names&suite=all&section=all except for a new build. The changelog http://changelogs.ubuntu.com/changelogs/pool/main/d/dvipng/dvipng_1.14-1build1/changelog says the new build is for some kpathsea transition.

The upstream author reports that this works in Linux Mint and thinks it could be some kpathsea problem: http://lists.nongnu.org/archive/html/dvipng/2013-06/msg00001.html. Surely in Kubuntu Precise there was no problem.

I'm not sure about Quantal since I never used it (directly came Precise->Raring). However I would imagine the same problem exists there because the dvipng version is the same.

Please fix this, thank you!

Turns out that the bug is partially topstream and partially in the Debian packaging. See http://lists.nongnu.org/archive/html/dvipng/2013-06/threads.html especially http://lists.nongnu.org/archive/html/dvipng/2013-06/msg00004.html.

The program as it stands depends on latex-xcolor, however the author intends to later on make it only a recommends and not a dependency. Until such time, it should be added as depends.

I have hence changed the bug title and linked to the upstream Debian bug I reported.

Thanks.
