Long Rails Stack Trace

I was looking at the RailsConf schedule, and saw the Rails web app that runs it fail with this longish stack trace. A few Rubyists sitting nearby commented that the application was not well configured, that usually Rails apps are configured in deployment to store such traces to a log, rather than spit them at the user. Their mistake is my gain though, as it provided fodder for this post.

This stack trace is considerably shorter than a typical Java web app stack trace. But it is not so good either, and it is an ominous sign that excessive complexity is making its way in to Rails.
