My first-ever bug reported to the WordPress Trac website has officially been patched! About two months ago while developing the Absolute Privacy WordPress plugin I noticed that trying to add new roles (ie subscriber, administrator, etc) often ended in frustrating PHP warnings. I found the problem and suggested a fix in the Trac ticket.

A few days ago Denis-de-Bernardy added a file implementing my suggested fix. It’s now been tesed and set to be included in 2.8 when it is released. So if you ever find a bug in the core WP files, make sure to report it in the Trac.
