Image Upload Problem

I’m having issues with simple image uploads in Magento admin area und
PHP 5.2.6 using FastCGI:

2009/04/21 07:44:33 [notice] 29743#0: 14130 "^(.)$" matches
“/index.php/admin/catalog_product_gallery/upload/key/ffabc43d7bd4801b5a9567478d1ab383/”,

HTTP/1.1”, host: “nginx.openstream.ch”

I tried different file sizes as small as 2kb, but nothing seems to work.

This is my PHP config: http://nginx.openstream.ch/phpinfo.php
