Some further information.... This issue is apparently caused by not passing enough parameters to the route helpers when you have nested resources. For example, I have a gallery, which has a nested image resource. When generating links in the view, I called the helper, but I didn't pass an array with both the gallery and the image, only the image.
The first time presenting the view would work; the second, I would get the stack trace, and from that point on the mongrel instance is hooped, and would not serve any content. It would have to be restarted. I've fixed the view, and the problem is now resolved. However, I'm concerned about being able to crash mongrel hard this way.....
