Dale,

I remember something odd like this from like 2 years ago ... did you 
delete a role that had been used previously for that user? If so, try 
re-adding even if its no longer used and see if that changes anything. 

Or maybe you could check the security settings for that folder (and all 
folders above) and see if there are orphaned roles and clean them up.

ps

Or you could upgrade to a more current version of Zope and maybe it will 
just go away ...
