16731,Unchecked array_merge() returns NULL in wp_update_user();,milan.chotai,,"I am running PHP version 5.3.3-1ubuntu9.3 and encountered a bug in a simple plug-in I wrote that worked up to Wordpress v3.0.5 but not in 3.1. It uses wp_update_user(), which is causing the issue. I traced the bug to line 1563 of wp-includes/user.php:

$userdata = array_merge($user, $userdata);

If $user is NULL, then array_merge returns NULL, making $userdata useless to other functions that follow like wp_insert_user().",defect (bug),new,normal,3.6,Users,3.1,normal,,has-patch,adambackstrom karacsi_maci
