Comment:

 Hi jmds,
 First of all, sorry you never received a response to this ticket.

 Without seeing code, it's hard to see what the actual problem you've run
 into was, but I'll take a guess based on the most common reason.
 When the plugins `uninstall.php` file is included, the plugin is not
 active, this means that any taxonomies and post_type's need to be
 registered upon `uninstall.php` being called. Simply including the main
 plugin file is often not enough either, as the `init` action has already
 been run, so usually the function/method responsible for registering the
 taxonomy needs to be called directly from `uninstall.php`.

 Another way of looking at it, is that `uninstall.php` is designed to be
 self-contained, it's not supposed to rely upon the plugin setting up the
 environment, and including the plugin automatically directly during
 uninstall can often lead to bugs with plugins that don't expect to work
 like that.

 If this sounds like the issue you ran into, this ticket can be safely
 closed I believe.
