Request exceeded the limit of 10 internal redirects due to probable configuration error.

I upgraded to Apache 2.4.10 and I am getting these errors for sites which used to work:

AH00124: 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.

One strange thing is these happen only with .htaccess files. So if I use exactly the same configuration but written in vhosts config file such as /etc/apache2/sites-enabled/000-default.conf all works well. So yes, one quick fix is to put it there. But after doing some tests, I found out apache 2.4 does not like when you redirect stuff to index.php but you don't have a rule for index.php itsels. So simply keeping all rules and adding something like RewriteRule ^index\.php$ - [L] fixed the problem.

[UPDATE] On many other cases it seems to work without any trouble or extra rule, but on that particular one not... strange.
