 Severity:  normal       |    Keywords:  wp_list_page walker
-------------------------+--------------------------------------------------
 When I view a page in 2.7-beta3-9817 the wp_list_pages throws up a warning
 in my test environment with both php 4 and 5.

 Warning: Cannot use a scalar value as an array in
 T:\hosts\wordpress\wordpress.trunk\wp-includes\classes.php on line 827

 $args[0] is set to page_id when you view a page and $args[1] is the place
 you're looking for at that point. Problem starts at line 623 post-
 template. $current_page is only set when on a page and PHP seems not to
 mind adding an named array to an array when the value is null or 0. Could
 set the value when not in a page to -1 so people see the problem sooner.
