A Google Groups thread suggests that Google should not only show the URL, the type of error and the date of the error in the web crawl error report within Google Sitemaps. It should also referrer data, so that the webmaster can better diagnose the issue. That will tell the webmaster the source of the error and be able to better resolve the issue.

Good to hear, I wonder how soon it will come?
