#0C:08 on reply with history

Now I am pretty ceratain I have seen this error before but I searched the forum and found nothing. I also searched the KB and got over 4000 searches with the same search. None of which looked like anything to do with the problem.

Any one know what causes #0C:08 on reply with history in the standard mail template?

Subject: #0C:08 on reply with history

Has anyone figured this one out? We are getting the same error message on mail replies with history.
