Issue MDL-30812: Latest backup files generate error/setting_invalid_ui_label upon restore
Administrators and staff are unable to restore recently created course backup files. Prior to the upgrade to 2.1.3 any backup file created can be restored into a new course even now. Since this upgrade the restore process goes through the steps, but upon pressing "restore" an error/setting_invalid_ui_label is generated and upon pressing continue the restored course is showing up as an invisible course in the process of being restored, but never completes. We did an upgrade to the latest Moodle version 2.2 but this did not alleviate the error. The problem appears to be with the creation of the backup file as any created since the upgrade to 2.1.3 is now generating the error/setting_invalid_ui_label and all backups created prior to 2.1.3 can still be restored successfully.
