The request has to be for a multisite subsite as the request has to pass through wp-includes/ms-files.php. The problem is caused by a call to wp_check_filetype that is passed an argument of $_SERVER!['REQUEST_URI'] rather than $file. Since this variable contains the querystring of the request, it causes a failure of the regular expressions that are used in wp_check_filetype function. This problem isn't present for all files as a fallback to mime_content_type is present, and that function is called with the correct argument. Files with extensions of CSS are good examples of the problem as the mime_content_type function returns a type of text/plain in these cases. However, I have seen some servers that will return content-types such as ""text/css?ver=1"". Attached is a patch that fixes this improper argument issue. It is built off of [15473]." defect (bug) closed normal 3.0.2 Multisite 3.0 normal fixed has-patch
