Trying to making work russian lang in TeX

Question

• Ubuntu 12.04.4 LTS
• PHP 5.3.10-1ubuntu3.11
• MediaWiki 1.16.5

I installed TeX themself and he works, but russian letters in \text{} not working, error: Failed to parse (PNG conversion failed; check for correct installation of latex, dvips, gs, and convert).

If I run command (/home/user/www/site.ru/math/texvc '/home/user/www/site.ru/images/tmp' '/home/user/www/site.ru/images/tmp' '\text{ пример }' 'utf-8' 'transparent') (user is same as in apache) from cmd it works! File in /home/user/www/site.ru/images/tmp exists. And output is cd7d4363323218b64410c10a0a2b46773 пример . Wich proving installation is correct.

When same command executed in MediaWiki, output is similar (cd7d4363323218b64410c10a0a2b46773 пример ), but file doesn't exists. In /home/user/www/site.ru/images/tmp folder appears log missfont.log with this contents:

mktextfm larm1200
mktextfm larm0800
mktextfm larm0600

I'm tried to run this commands but it change nothing. I even tried create test.php and test without CMS. Result is same as in MediaWiki (missfont.log created in temp).

PS In Ubuntu 9.10 russian lang in \text{} worked. I added in texutil.ml russian babel "\usepackage[russian]{babel}\n\usepackage{cancel}\n\pagestyle{empty}\n\begin{document}\n$$\n" and recompile sources. And did some changes in Math.php (with locals). Also I downloaded latest Math extension and replaced math folder. Read more here.

Problem was in system variable HOME. So to fix you need to add in LocalSettings.php line putenv('HOME=/home/user'); (with your user home dir).
