Не работает довольно стандартный набор правил для мод-реврайта

(.htaccess в директории ./rewrite/)

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /rewrite/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /rewrite/index.php [L]
</IfModule>

даёт 500ю Internal Server Error, вот лог аппача

Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

т.е. петля получилась почему то :(

поставил
RewriteLogLevel 3

вот одна из "попыток" из лога мод-реврайта

strip per-dir prefix: /var/vhosts/domain.com/httpdocs/proxy5/index.php -> index.php
applying pattern '.' to uri 'index.php'
