WP_DEBUG causes PHP warnings

Hi,
WordPress generates deprecation notices if I set WB_DEBUG to true.
The deprecated function calls are:

• load_plugin_textdomain
• register_sidebar_widget
• register_widget_control
• register_sidebar_widget

On newer WP versions there are maybe more warnings.

In addition, I get the following PHP notice:

Notice: Undefined index: statpress_action in /var/www/wordpress/wp-content/plugins/statpress/statpress.php on line 149

If you do not have much time, I can maybe write a patch some day.
