Description Suvayu 2010-10-09 03:55:47 UTC 
Description of problem:
The script /usr/bin/texinfo2dvi from the sub-package (texinfo-tex) uses a regex (line # 1686) which is incompatible with the latest version of egrep distributed with Fedora 13 (GNU grep 2.6.3 from grep-2.6.3-1.fc13). This leads to the the script failing when run in locales other than "C".

Version-Release number of selected component (if applicable):
texinfo-4.13a-10.fc13.src.rpm

How reproducible:
Always

Steps to Reproduce:
1. Create a basic TeX file
2. Run `texi2dvi -p -b -c -V texfile.tex'
3. The script will exit with an error
  
Actual results:
Script fails

Expected results:
Script successfully runs latex/pdflatex to generate desired document.

Additional info:
This is a know issue which is caused by a stricter checking by the new version of egrep. The regex in question actually checks for the full path of the file (including drive letters for windows systems). With the latest version of egrep this check results in an error message like this,

$ echo "$filename" | egrep '^(/|[A-z]:/)'
egrep: Invalid range end

This has been discussed and fixed upstream.[1] This change also breaks the latex to pdf export in the HEAD version of org-mode (GNU Emacs package).[2]

It would be really helpful if this could be fixed in the Fedora release of texinfo. Maybe as a Fedora patch if there is no new release of texinfo in the near future?

Thanks a lot.
