 Drupal 7.22, xxxx-xx-xx (development version)
 -----------------------
+- Fixed incorrect log message when theme() is called for a theme hook that does
+  not exist (minor string change).
 - Fixed Drupal's token-replacement system to allow spaces in the token value.
 - Changed the default behavior after a user creates a node they do not have
   access to view. The user will now be redirected to the front page rather than

includes/theme.inc
