Exception Error when Deleting Partners in 1065

[beccad]

We are having an issue with deleting partners in 1065s.  Once one is deleted and you try to add a different on an exception error pops up and then more errors continue to pop up.  After that  you are unable to add partners at all and any info in the partner screen is blank.  It just keeps throwing errors.  Does anyone else have this issue?  It is repeatable.  Does not happen in any other module.
