Novell ZENworks 10 Configuration Management Bundles
Bundle has "Display Message " action
ERROR: "There was an unspecified error in Display Message Handler " in zmd-messages.log
Bundle is launched when no user is logged in
A fix for this issue is included in ZENworks 11, see KB 7006995 "ZENworks 11 - information and updates" which can be found at https://www.novell.com/support
The message occurs because the "Display Message " action cannot be successfully completed when there is no user to display the message to.
