MS WS 2003 EE with Terminal services. ZCM Agent 10.1.3.

Some times ZCM Agent was not responding (not crash). In logs I found this entries:
[DEBUG] [03/23/2009 09:53:43.125] [948] [ZenworksWindowsService] [14] [] [BundleManager] [] [Unexpected exception deserializing appState for bundle 6e7d8dc7a41a7da803a23e6cc28b3c4c: Item has already been added. Key in dictionary: 'mdegtyar' Key being added: 'mdegtyar'

Anyone know what it is?
