 This becomes a problem when editing posts on sites with no capable users.
 Technically, an empty string is the expected result, as the site has no
 users with adequate capabilities to assign as the author of a post. (I'll
 propose 1 solution in a comment below.)

 To duplicate:

 * Setup multisite
 * Create a second site
 * Add a user to it as a Subscriber
 * Remove yourself from that site, if necessary
 * Edit the "Hello World" post
 * Notice the "Author" metabox is empty
