Undefined index: in CRM_UF_Page_Group::extractGroupTypes() line 489

After upgrading to 4.5.6 I am getting the following error message on the Administer-Custom Data-Profiles page

Notice: Undefined index: in CRM_UF_Page_Group::extractGroupTypes() (line 489 of ***/sites/all/modules/civicrm/CRM/UF/Page/Group.php).

Line 489 is the second if statement here:

Code: [Select]

foreach ($valueParts as $val) {
          if (CRM_Utils_Rule::integer($val)) {
            $groupTypeValues[$val] = CRM_Utils_Array::value($val, $valueLabels);
          }
        }

        if (!is_array($returnGroupTypes[$typeName])) {
          $returnGroupTypes[$typeName] = array();
        }
        $returnGroupTypes[$typeName][$valueParts[0]] = $groupTypeValues;
After the upgrade, we had some issues with some custom Participant Data Fields similar to this issue: https://issues.civicrm.org/jira/browse/CRM-15427

And since the upgrade, we have also installed the Youth Registration Extension, but I have no specific evidence that either of these are related to the message above.

Any ideas?
