[Plugin: Dynamic Widgets] PHP Notice

On taxonomy archive pages we get a PHP notice:

Notice: Undefined property: stdClass::$post_name in /home/thielska/public_html/wp-includes/theme.php on line 956

Without looking too deeply in the plugin code, it appears you call “get_page_template()” even when it is not a page.
