--------------------------+-----------------------------
 When passing an empty string as $blogname (and $blog_title, for the
 record) in wpmu_validate_blog_signup(), there is an empty() check, and an
 error is registered with the WP_Error object.

 However, a PHP notice is generated by the nearby "$blogname != $maybe[0]"
 check. PHP reports that $maybe[0] is undefined.

 (This was tested on WP 3.1.1)
