Sharepoint Backup Error KeyNotFoundException: The given key was not present in the dictionary

I have a Sharepoint 2007 server, and when I try use the central admin to do a backup of the farm, it is failing with
Object Sharpoint <site> KeyNotFoundException: The given key was not present in the dictionary.

The services accounts and permissions are 100% ok so it's something else, any ideas ?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

KeyNotFoundException usually means something is "Corrupt". Am not saying it can not be recovered but best bet would be to contact Microsoft for this issue.
