11548	Possible to create a user with an empty user_login using wp_insert_user	westi	westi	"The code in wp_insert_user does not check to see if the sanitised name which will be used for user_login is actually a useful username.

It is therefore possible to end up with a user with an empty user_login which is not much use.

This is hilighted by #10319 which talk about issues with the import and non-ascii usernames.

The purpose of this ticket is to fix wp_insert_user to stop the users getting created."	defect (bug)	closed	normal	3.0	Users	2.8	normal	fixed
