The main use case for showing old user (not system) related crashes after login are crashes from cron, screen, and remote sessions. However, the are certainly a corner case, and for stable releases I'd go as far as ignoring them entirely. This would be a simple and safe SRUable change. Telling them apart from legitimate crashes from remote/noninteractive sessions is a lot more difficult, and I don't have a good off-hand idea how to do that.
