Same here.

I have the exact same issue here in an upgraded Magento shop 1.5 to 1.7.
I applied the index fix but now this one started appearing as from today.
Will have a look into it as there is no fix yet.

Arg.. almost all config items give this error when opening them on the frontend... Still no solution.
