Wordpress Version: WordPress 2.1.2 (also checked that 2.1.3 has the same bug)
Problem File: wp-admin/link-manager.php
Problem Line: Line 183
Problem: The variable $id is not defined (ie: var_dump($id)=NULL). Based on preceding code and documentation in Codex about how it's supposed to work, I think it should be $link->link_id
Reason for fixing: Required for those who are making plugins relating to the blogroll administration. Also, why leave a typo like that in?
Original Code (Line 183):
<td><?php do_action('manage_link_custom_column', $column_name, $id); ?></td>
Proposed solution (Line 183):
<td><?php do_action('manage_link_custom_column', $column_name, $link->link_id); ?></td>
Error is confirmed to appear on (it should appear always, since it's a code flaw/typo):
