I don’t think we can just ignore the -2 issue, because I think that it points to a larger confusion between `user_nicename` and `user_login` on your installation. I’m not sure what kind of further debugging can be easily done at this point, though, without direct access to your system. I guess I would check a couple of things if this were my system:

– Drop some debug `var_dump()`s around https://buddypress.trac.wordpress.org/browser/tags/1.5.4/bp-core/bp-core-catchuri.php#L239, to see how BP is determining your displayed user ID
– Check directly in your database to see if there is some strangeness in the way that your user_nicename is defined in wp_users. The nicename should not contain capital letters or spaces, though user_login can.
