Comment:

 I've disabled the mbstring extension on my install to force the compat
 version to run instead, but still could not reproduce the issue.

 `mb_substr()` is called via `wp_html_excerpt()` for the blog name in
 Toolbar. If the blog name is empty, the host name is used instead: [[BR]]
 http://core.trac.wordpress.org/browser/tags/3.5.1/wp-includes/admin-
 bar.php#L219

 What's the value of `$blogname` in your case?
