@rmaddy - Though I've got to give him a bit of credit for actually including the entire message, vs just paraphrasing it. Given that the critical info is at the very right end of the first long line this is extremely useful. — Hot Licks, Apr 11 '14 at 20:53

It means that in a nib file you have an outlet called DescriptionLablel, but you don't have a property for it in your code. "Label" is misspelled, so that could be your problem.
