After I PM'd you and didn't get a response I had someone else look into this issue. This is the code they came up with...

	$messagetext = preg_replace_callback(
		'#(^|\[/(' . $skiptaglist . ')\])(.*(\[(' . $skiptaglist . ')\]|$))#siU',
		function ($matches)
		{
			return convert_url_to_bbcode_callback_auto_title($matches[3], $matches[1]);
		},
		$messagetext
	);

I haven't tested your code but I know for certain that the one above works as I'm currently using it in a production environment.

Looks like the same code to me just a different variable name correct?
