Hi,

I've just noticed that the file command returns wrong mime for a file.
In fact, if a LaTeX file uses the command \bibligraphystyle somewhere
in the beginning, file will return mime "text/vnd.graphviz" instead of
"text/x-tex". I took a look at /usr/share/file/magic (on Lenny), and
it has something like :

0 regex/100 [\r\n\t\ ]*graph[\r\n\t\ ]*.*\\{ graphviz graph text
!:mime text/vnd.graphviz

This regular expression matches \biblioGRAPHystyle in the first
thousand characters or so. A good fix would be :

- 0 regex/100 [\r\n\t\ ]*graph[\r\n\t\ ]*.*\\{ graphviz graph text
+ 0 regex/100 (^|[\r\n\t\ ]+)graph[\r\n\t\ ]*.*\\{ graphviz graph text

Since in the dot file format[1], the keyword "graph" must be preceded
by a white space or be in the beginning of the file.

Anyone knows where I can report this?

I think this belongs to package 'file'...

According to the packages page on the Debian web site, /usr/share/file/magic
belongs to package libmagic1. I would suggest filing a bug report against
package libmagic1.

Yup, source package file is the best place. See
<http://www.debian.org/Bugs/Reporting> if you need info on
how to report bugs in Debian.

You already have the answer, but here are two more ways:

$ dpkg -S /your/buggy/file

or even

$ reportbug /your/buggy/file

(reportbug uses dpkg -S AFAIK).
