I think I had told them that I narrowed it down to that line, as they specifically offered to help me debug it. I said I got the error pinned down to line X, but still... It might have been a fluke, though, as I think there was one person who instigated this whole bad treatment. Apparently he was well-known for it, because someone said something like "heh, hell will freeze over before X will just hand out a solution".
