12776	new ms site sometimes gets no roles	RogerTheriault		"After upgrading to WPMU 2.9.2 from 2.8.6, we experienced a strange issue with NEW blogs - the blog's wp_xx_user_roles option was not adequately populated. There were no warnings, complaints, or errors at blog creation time.

Symptoms: 
 * the admin could not access the new blog's admin side (the exact message is ""You don't have permission to view this blog. Please contact the system administrator."")
 * the Add New User admin panel (for a site admin) only displays the role ""Administrator"" in the drop-down
 * the wp_xxx_user_roles blog option contains only one ""administrator"" role with no capabilities (except those added by active plugins)

Looking at the install_blog function in wp-includes/wpmu-functions.php, it seems the order of function calls suddenly matters, once we changed it to the below, we were able to create new blogs with correct user roles:

{{{
        $wp_roles->_init();
        populate_roles();
}}}

The init function sets the option key for the roles but will not save anything to the db if the global $wp_user_roles already exists.

Environment: 
 * Have not tested against trunk 
 * we suspect it may not manifest itself in every installation. 
 * We do have plugins installed that add capabilities (eg: wp-polls) but those did not cause any issues in 2.8.6.
 * we are using memcached

Steps to reproduce: 
 * create a new blog and administrator using the form at the bottom of the Blogs list (as a site admin)
 * using the new admin's credentials, attempt to access the new blog's admin page, eg: http://somesite.com/newblogname/wp-admin/
 * the admin is denied access and debugging indicates the user has no ""read"" or ""edit_user"" capabilities
 * Note: site uber-admins can still access the new blog's admin pages

Workaround:
 * copy the serialized array from the wp_xxx_user_roles option of another blog to the new blog."	defect (bug)	closed	normal		Multisite	2.9.2	major	worksforme		RogerTheriault
