Overwrite errors: "Internal server error" (error.log inside)

I upgraded the old eZ-Publish website to the latest version 4.6 of PHP5 (previously in PHP4). The site runs on my local web server, but when I try to execute it on the server, the following message fails in Apache error.log:

[Mon Apr 16 14:33:22 2012] [error] [client 46.249.225.2] Request exceeded the limit of 20 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

I narrowed it down to a problem in the rewrite rules, which is strange because I use the same rewrite rules as the other 4.6 settings. Here are the rewrite rules in the Apache host file:

RewriteEngine On
Rewriterule ^/var/storage/.* - [L]
Rewriterule ^/var/[^/]+/storage/.* - [L]
#RewriteRule ^/var/cache/texttoimage/.* - [L]

# Uncomment the following lines when using popup style debug.
# RewriteRule ^/var/cache/debug.html.* - [L]
# RewriteRule ^/var/[^/]+/cache/debug.html.* - [L]
RewriteRule .* /index.php

Are there any problems?
