$wp_taxonomies['category'] = (object) array('name' => 'category', 'object_type' => 'post', 'hierarchical' => true, 'update_count_callback' => '_update_post_term_count');
$wp_taxonomies['post_tag'] = (object) array('name' => 'post_tag', 'object_type' => 'post', 'hierarchical' => false, 'update_count_callback' => '_update_post_term_count');
$wp_taxonomies['link_category'] = (object) array('name' => 'link_category', 'object_type' => 'link', 'hierarchical' => false);

Since I don’t get any error messages neither on the screen nor in the log files I have no idea why these casts fail. The PHP version used to serve the site is the latest stable 5.x release from php.net.
As a workaround I introduced a function that does also transforms an array into an object but does not rely on the casting mechanism.

function arr2obj($arr) {
	foreach ($arr as $k => $v) $obj -> {$k} = $v;
	return $obj;
}

$wp_taxonomies['category'] = arr2obj(array('name' => 'category', 'object_type' => 'post', 'hierarchical' => true, 'update_count_callback' => '_update_post_term_count'));
$wp_taxonomies['post_tag'] = arr2obj(array('name' => 'post_tag', 'object_type' => 'post', 'hierarchical' => false, 'update_count_callback' => '_update_post_term_count'));
$wp_taxonomies['link_category'] = arr2obj(array('name' => 'link_category', 'object_type' => 'link', 'hierarchical' => false));

To cut a long story short, eventually I came across this PHP bug report #42739 mkdir doesn’t like a trailing slash when safe_mode is enabled and it turned out that this was the issue I was facing with on my hosting account too. The safe_mode option is enabled and WordPress tries to create directories that end with a slash (e.g. /htdocs/wp-content/upgrade/the-plugin/).

After knowing the reason I could develop a workaround and finally got the one-click updater running. If you are facing the same issue you can try to use my patch too.

1. Locate and open the file <wp_root>/wp_admin/includes/class-wp-filesystem-direct.php in an editor
   
2. Search for “function mkdir”
   
3. Add the following statements to this method

   function mkdir($path,$chmod=false,$chown=false,$chgrp=false){
   	if( ! $chmod)
   		$chmod = $this->permission;
   
   	// workaround for http://bugs.php.net/bug.php?id=42739 starts here
   	if(ini_get('safe_mode') && substr($path, -1) == '/')
   	{
   		$path = substr($path, 0, -1);
   	}
   	// workaround for http://bugs.php.net/bug.php?id=42739 ends here
   
   	if( !@mkdir($path,$chmod) )
   		return false;
   	if( $chown )
   		$this->chown($path,$chown);
   	if( $chgrp )
   		$this->chgrp($path,$chgrp);
   	return true;
   }

4. Start one-click updating!

Addendum:

1. The patch also works for WordPress 2.5.1
2. If applying this patch does not lead to success the problem may have a second cause. Therefore also check the permissions on the /wp-content/upgrade/ folder and it’s sub folders, e.g. chmod them to 777. If the upgrade directory does not exist at all it may be sufficient to create it manually.
