Hey guys, I recently upgraded to 4.x (4.0.5 atm) and I noticed some bugs.

The first one is about PHP_SELF "Can't identify current .php script name in PHP_SELF.", it looks like its caused by the regex.
See http://idl0r.qasl.de/ this is currently a redirect to http://idl0r.qasl.de/blog/ . I know I should redirect to the index.php rather but it should also work without explicit adding the index.php.

The second one is regarding the MySQL error 2006 (MySQL server has gone away(Errno=2006)) which is thrown on almost each page. I read some other threads here but I couldn't find a solution. And no, it's not a MySQL server issue like some assumed in other posts.

Everything worked fine with the latest 3.x version.

I don't think its relevant but anyway:
PHP 5.3.6 (via suPHP)
MySQL 5.1.51

Esp. the MySQL error is annoying and I'd be glad about a fix.
