 In WP 3.3 Beta 3, activating a plugin that registers custom meta boxes
 makes the web site go to a blank screen with the error:

 Fatal error: Call to undefined function convert_to_screen() in
 C:\Home\Projects\htdocs\wp-admin\includes\template.php on line 854

 Looking at this line, it is trying to call the function convert_to_screen
 to convert the name of the screen that meta box should be displayed on,
 since it is passed as one of the function arguments.

 In this specific case, it happened upon trying to activate the Link
 Library plugin (http://wordpress.org/extend/plugins/link-library/)
