No. The only obvious thing to do is keep ruling out attributes one at a time and file a bug so we get the header name logged. If it had ever happened in 20 years it would be logged already but the error check is pro forma, there's nothing documented by MS that would cause it to fail.

You can also file a bug and attach a trace of the response so somebody can reproduce the issue, but being that you're not a member, that's not going to happen outside of the ordinary course of development, which means many months as there are no SP releases planned.
