CNA: "Error: VLANs" "Index: 0, Size: 0" ?

[Just Someone YKnow]

Does anyone know what is causing this? I see this on:

- Cisco Network Assistant v5.8.5.1

- Cisco Network Assistant v5.8.9.1

When I click OK, the VLAN dialog is blank, but if I click Refresh it updates and shows them. I'm afraid to actually edit anything via CNA, as I don't know if CNA is malfunctioning due to the initial error, and may destroy the running config.

I was not aware that CNA did application logging, but I see this in my user profile:

Application_Log_Wed_May_21_11_17_19_CDT_2014-1400689039821

This appears to be the relevant errors. There are no times on these log entries so I don't know if this is exactly it:
