My thought is that it is not fatal error or that the bike will explode, but I just wonder if it may start up again along that same line. The seat post sits all the way down and the forces I would think not be enough to do anything. I don't use this as my everyday riding bike but it really is a decent frame and I hate to say it is worthless now.
