Error: get_theme_data is obsolete since version 3.4

Hello.
I just did a manual update of WordPress from 3.2 to 3.4, because the automatic update kept failing. I followed all the directions in the Codex and now I’m seeing this message on the top of the site and dashboard:

Notice: get_theme_data is obsolete since version 3.4! Use wp_get_theme() instead. in /home/#/www/wp-includes/functions.php on line 2628

I opened that file and here’s what I found on line 2628:

trigger_error( sprintf( __(‘%1$s is deprecated since version %2$s! Use %3$s instead.’), $function, $version, $replacement ) );

Would you know how else I could fix this error or what I could do about it?

Thanks!
